<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=870</link>
<description><![CDATA[Complex adaptive systems are dynamically assembled systems characterized by multiple competing stakeholders, fluid requirements, emergent behavior, and susceptibility to external pressures that can cause change across the entire system. This paper shows how key principles of complex systems engineering can support achieving net centric operations (NCO) for the DoD. We discuss approaches to on-demand data, an IT infrastructure strategy based on web service and semantic web technologies, as well as guidance and initial observations on spiral development and management using Communities of Interest combined with a Developer&amp;rsquo;s  Environment.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=871</link>
<description><![CDATA[The introduction of the Semantic Web paradigm in Service-oriented Architectures enables explicit representation and reasoning about services, via a semantically rich description of their operations. We propose an approach towards service selection and composition based upon the interpretation of user requests expressed through an informal humancomputer interaction interface that employs (restricted) Natural Language.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=754</link>
<description><![CDATA[Improving service quality has long been recognized as a key business strategy in consumer market. However, little is written in the literature about service among business organizations. The shortage of knowledge on business service (BS) poses a significant challenge in tracking and improving BS quality in today’s e-commerce environment. To address this, this paper takes a first step to identify main BS dimensions in an e-commerce environment. It first provides a review on BS. Then the BS gap model and main BS dimension are identified. The paper concludes with a summary and future research suggestions. <a href="http://csdl.computer.org/comp/proceedings/icws/2005/2409/00/24090787.pdf">Full Article Text</a> <strong>DOI Bookmark: </strong>http://doi.ieeecomputersociety.org/10.1109/ICWS.2005.73?<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=747</link>
<description><![CDATA[Although EDI (electronic data Interchange) have provided a useful method to the automated message Interchanging between enterprises, this method costs a lot of money and resources, there is a new technology named ebXML(Electronic Business using eXtensible Markup Language) BPSS(Business Process Specification Schema) which provides a more easy way to integrate the whole business process. Ebxml BPSS supports the specification of the set of elements required to configure a runtime system in order to execute a set of ebXML business transactions. Ebxml BPSS describes which message should be interchanged and how to interchange, and provides a set of specification for the process automation. In this study, we propose a federated multi-agents system, which can implement the business process, and describe a detailed mechanism to apply the BPS to a prototype implementation.<a href="http://csdl.computer.org/comp/proceedings/icws/2005/2409/00/24090779.pdf">Full Article Text</a><strong>? </strong>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=216</link>
<description><![CDATA[Service directories are a key component of distributed systems where shared information must be managed effi- ciently. For a directory with a large numbers of entries, the result set of a query may be large, too. In this case it is important to order the results according to heuristics and to retrieve them incrementally. Our contribution is an integrated directory system specially adapted to large-scale service discovery and composition. We introduce DirQL, a flexible query language for the matching and ranking of service descriptions. As results are incrementally retrieved, our system is able to lazily compute the result set based on: 1) the organization of the directory as a special balanced search tree that has an extra "intersection" discriminator, 2) a scheme for transforming the original query into one taking into account the tree structure of the directory, and 3) the organization of partial results in a heap structure sorted according to the transformed query. We also report on experimental results regarding the usage of the directory by a composition engine solving randomly generated problems. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.62">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=217</link>
<description><![CDATA[In this paper, we explore the use of domainindependent and domain-specific ontologies to find matching service descriptions. The domainindependent relationships are derived using an English thesaurus after tokenization and part-of-speech tagging. The domain-specific ontological similarity is derived by an inference on the semantic annotations associated with web service descriptions. Matches due to the two cues are combined to determine an overall semantic similarity score. By combining multiple cues, we show that better relevancy results can be obtained for service matches from a large repository, than could be obtained using any one cue alone. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.102">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=218</link>
<description><![CDATA[Complex services are composed of simple services which typically need to be processed in a particular order. Two complex services only match if they agree on both, their simple services and their processing order. This matching semantics can be formalized by means of modelling complex services as finite state automata (FSAs), and analysing the intersection of the FSAs. However, computing the intersection of FSAs is computationally expensive, and thus does not scale for large service repositories. This paper presents an approach for indexing and matching complex services using an abstraction that transforms the underlying FSA via its grammar into a form that can be indexed using available index mechanisms. Evaluation of this approach shows a performance gain of several orders of magnitude as compared to sequential matching.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.6">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=219</link>
<description><![CDATA[The Sloan Digital Sky Survey (SDSS) science database describes over 230 million objects and is over 1.6 TB in size. The SDSS Catalog Archive Server (CAS) provides several levels of query interface to the SDSS data via the SkyServer website. Most queries execute in seconds or minutes. However, some queries can take hours or days, either because they require non-index scans of the largest tables, or because they request very large result sets, or because they represent very complex aggregations of the data. These "monster queries" not only take a long time, they also affect response times for everyone else-- one or more of them can clog the entire system. To ameliorate this problem, we developed a multi-server multi-queue batch job submission, execution, and tracking system for the CAS called CasJobs. The transfer of very large result sets from queries over the network is another serious problem. Statistics suggested that much of this data transfer is unnecessary; users would prefer to store results locally in order to allow further joins and filtering. To allow local analysis, a system was developed that gives users their own personal databases (MyDB) at the server side. Users may transfer data to their MyDB, and then perform further analysis before extracting it to their own machine. MyDB tables also provide a convenient way to share results of queries with collaborators without downloading them. CasJobs is built using SOAP XML Web services and has been in operation since May 2004.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.29">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=227</link>
<description><![CDATA[High Energy Physics (HEP) and other scientific communities have adopted Service Oriented Architectures (SOA) [1][2] as part of a larger Grid computing effort. This effort involves the integration of many legacy applications and programming libraries into a SOA framework. The Grid Analysis Environment (GAE) [3] is such a service oriented architecture based on the Clarens Grid Services Framework [4][5] and is being developed as part of the Compact Muon Solenoid (CMS) [6] experiment at the Large Hadron Collider (LHC) [7] at European Laboratory for Particle Physics (CERN) [8]. Clarens provides a set of authorization, access control, and discovery services, as well as XMLRPC and SOAP access to all deployed services. Two implementations of the Clarens Web Services Framework (Python and Java) offer integration possibilities for a wide range of programming languages. This paper describes the Java implementation of the Clarens Web Services Framework called ‘JClarens.’ and several web services of interest to the scientific and Grid community that have been deployed using JClarens.  <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.71">buy now!</a><div></div><div></div>]]></description>

<item><title><![CDATA[Improving Web Service QoS for Wireless Pervasive Devices]]></title>
<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=228</link>
<description><![CDATA[The web services enable interaction among remote and diverse applications running on disparate platforms. While the service providers offer generic service response to meet the requirements of diverse client applications, it is the responsibility of the application to extract relevant data from the response. This causes performance overheads for power and network bandwidth limited pervasive devices due to networking and parsing excess data. It is thus important for services and pervasive applications to interact in a way that optimally utilizes the resources of the pervasive device. In this paper we describe an efficient interaction methodology between web services and pervasive applications that optimizes the service quality for the device. We extend the quality of service definition beyond service response time to include power and airtime utilization and allow pervasive applications to be aware about it to dynamically adapt to the services and the available resources of the device in realtime.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.69">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=229</link>
<description><![CDATA[Quality of Service (QoS) support in web services plays a great role for the success of this emerging technology. In this paper, we present a QoS brokerbased architecture for web services. The main goal of the architecture is to support the client in selecting web services based on his/her required QoS. To achieve this goal, we propose a two-phase verification technique that is performed by a third party broker. The first phase consists of syntactic and semantic verification of the service interface description including the QoS parameters description. The second phase consists of applying a measurement technique to compute the QoS metrics stated in the service interface and compares their values with the claimed one. This is used to verify the conformity of a web service from the QoS point of view (QoS testing). A methodological approach to generate QoS test cases, as input to QoS verification is used. We have implemented a prototype that includes the verification and certification components of the broker. We performed experiments to evaluate the importance of verification and certification features in the selection process using real web services.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.13">buy now</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=230</link>
<description><![CDATA[User authentication is a crucial security component for most computing systems. But since the security needs of different systems vary widely, authentication mechanisms are similarly diverse. In particular, independently managed Web and Grid Services vary with regard to the type of security token (credential) used to prove user identity (username/password, X.509 signing, Kerberos, etc.). Forcing users to manage and present credentials manually for each service is tedious, error-prone and potentially insecure. In contrast, we present CredEx, an open-source, standards-based Web Service that facilitates the secure storage of credentials and enables the dynamic exchange of different credential types using the WS-Trust token exchange protocol. With CredEx, a user can achieve single sign-on by acquiring a single (default) credential then dynamically exchanging that credential as needed for services that authenticate a different way. We describe the design and implementation of CredEx by focusing on its use in bridging password-based Web Services and PKI-based Grid Services, illustrating how interoperability between these realms can be based upon the WS-Security and WS-Trust specifications. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.43">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=231</link>
<description><![CDATA[The infiltration of the Web as the preferred choice for online e-commerce and IT applications has motivated the need to introduce innovative mechanisms to enforce strong security monitoring and control on transactions conducted over a distributed environment. The smart card technology presents an attractive solution for providing strong security and access control mechanisms that are tightly bound and associated to the individual carrying and owning the card. Despite its potential, smart card services have not been integrated into the networked environment in the way other portable computing devices, such as notebooks, PDA, mobile phones, and so on, have been. This has motivated our design for a distributed computing platform for smart card services to operate over a service- oriented architecture (SOA) based on evolving Web Services technology. In particular, the paper presents the design of the WSCard (in short for Web Services Card) architecture and its implementation based on the application of web services wrapping technology. Importantly, the design allows us to exploit Web Services flexibility to provide a heterogeneous and promote rapid integration of smart card services as first class citizens of web services. With WSCard, existing service-oriented applications can seamlessly interoperate with smart card services by treating the card services as native web services, while employing established web services standards -- SOAP, WSDL and UDDI. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.134">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=232</link>
<description><![CDATA[As mobile devices become more pervasive they will emerge as a standard platform for hosting Web Service clients. Unlike their "static" counterparts, mobile devices are typically connected via a wireless network forcing them to deal with constrained bandwidth and the sudden loss of connectivity. This paper focuses on the use of caching SOAP request-response pairs in order to compensate for fluctuating bandwidth and loss of connectivity. We introduce the concept of embedded SOAP caching, highlighting the need for meta-data as a means to support it. A novel SOAP cache (CRISP) that can be embedded into the application or used as an independent proxy-cache is presented and evaluated under various loads and settings. The evaluation of CRISP shows that caching of SOAP traffic is not only an effective means to compensate for loss of connectivity but also enables reducing network loads which is particularly interesting when dealing with bandwidth constraint wireless connections. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.123">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=233</link>
<description><![CDATA[Web services technology has emerged as a key infrastructure that enables business entities to interact with each other without any human inventions. In order for the technology to be widely used, especially in any field where a large volume of transactions may be processed, it is highly desirable that the Web services engine should tolerate such environments. In this paper, we present a novel approach for improving Web services performance. We first focus on the fundamental characteristics of the Web services in that the SOAP messages on the wire are mostly generated by machines and have a lot of similarities among the processed messages. By making use of these features and eliminating the redundant processing, we propose a new deserialization mechanism that reuses matching regions from the previously deserialized application objects from earlier messages, and only performs deserialization for a new region that would not be processed before. Through our experiments in this paper, we observed that our approach obtained a 288% performance gain (maximum) by incorporating the differential deserialization into the Axis SOAP engine. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.87">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=234</link>
<description><![CDATA[Within the past years the web service technology emerged into more and more fields of application. In some cases the classical approach of using HTTP as a transport binding for SOAP seems no longer adequate. As a full scale application protocol HTTP causes a high amount of protocol overhead and is too inflexible for many web service scenarios. In this paper we will initially give an in-depth review of existing transport bindings with a strong focus on data rate efficiency. Then we will introduce an advanced UDP binding called PURE that significantly reduces the protocol overhead and enables interesting additional features such as point-to-multipoint communication via IP multicast and broadcast.  <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.53">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=235</link>
<description><![CDATA[Service composition based on state dependent services is a challenge if it done in a decentralized way, that is without a centralized coordinating partner knowing all involved parties. In particular, the challenge is the combination of services to a composite service, such that every party involved considers its view of the composite service to be acceptable. In the paper a protocol is proposed which incrementally derives proposals for composite services. These proposals are then evaluated by the involved parties locally and a consensus on the local decision on accepting or rejecting the proposed composite service is derived. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.46">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=236</link>
<description><![CDATA[A composite service is typically specified using a language such as BPEL4WS and orchestrated by a single coordinator node in a centralized manner. The coordinator receives the client request, makes the required data transformations and invokes the component web services as per the specification. However, in certain scenarios businesses might want to impose restrictions on access to the data they provide or the source from which they can accept data. Centralized orchestration can lead to violation of these data flow constraints as the central coordinator has access to the input and output data of all the component web services. In many cases existing methods of data encryption and authentication are not sufficient to handle such constraints. These data flow constraints, thus, present obstacles for composite web service orchestration. In this paper we propose a solution for orchestrating composite web services under data flow constraints. The solution is based on decentralized orchestration, in which a composite web service is broken into a set of partitions, one partition per component web service. To overcome data flow constraints, each partition is executed within the same domain as the corresponding component web service and hence, has the same access rights. However, there are, in general, many ways to decentralize a composite web service. We apply a rule based filtering mechanism to choose a set of partitions that does not violate the specified data flow constraints. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.88">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=237</link>
<description><![CDATA[Service-oriented computing has emerged as a new component-based software development paradigm in a network-centric environment. By using a standard description language and protocol, services can be used to wrap legacy software systems to be integrated beyond the enterprise boundary across heterogeneous platforms. Nevertheless, the challenges come in tandem with the opportunities because of the inherent dynamic characteristics within a distributed environment. In particular, there is a need for dynamic adaptation for provisioned services to accommodate the ever-changing business requirements externally as well as the computing resource status internally, while maintaining the continuousness of service provisioning. We present a dynamic Web Service provisioning approach based on .NET Common Language Runtime, one of the two primary Web Services platforms, exploring the runtime code manipulation at the Intermediate Language (IL) level rather than at the source code level. Meanwhile, we show how the service provisioning can be adapted in a modularized way by complementing the conventional Service-Oriented Architecture (SOA) with a repository of adaptation aspects.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=238</link>
<description><![CDATA[A Service Level Agreement (SLA) is a service contract that includes the evaluation criteria for agreed service quality standards. Since agreeable specifications on the evaluation criteria cannot be limited in practice, competitive SLA management products must be extensible in terms of their support for contract-specific SLA compliance evaluations. While the need of running and managing those software products as services increases, we have found that developing a good solution for configuring them as per contractual terms is a challenging task. This paper presents the Fresco framework, which facilitates configuring extensible SLA management systems using Web Services. An XML- based specification of SLA management related data called SCOL will also be presented to show how the framework supports contract- specific SLA terms and contract-specific extensions of the deployed SLA management software. The paper furthermore shows how the Fresco system uses a template-based approach to communicate with other Web Services applications with support for various input and output formats. Our experience with implementing the Fresco framework for a leading commercial SLA management software product demonstrates that the framework facilitates the creation of effective and efficient solutions for configuring extensible SLA management systems. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.141">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Web Services Proxy is an extendable intermediate that can monitor and control XML communication with good performance. It adopts a plug-in architecture enhanced by characteristic techniques named "MFI4P" and "XPath centric architecture." MFI4P efficiently controls plug-in libraries over various XML operations by optimizing transformation cost of XML between the libraries. The XPath centric architecture performs XML processing better and makes it easy to develop plug-in by using Streaming XPath and "two phase rule evaluation." Experimental results show many types of management functions can be built as plug-ins and XML processing overhead is minimized in many cases. <a href=-"http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.135">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=241</link>
<description><![CDATA[The configuration of a service-based system has a significant impact on the non-functional requirements of the system as a whole. However, finding the best configuration is very challenging and sometimes impossible for administrators because so many factors have to be considered. More importantly, a service based system has to be frequently reconfigured to adapt to rapid and continuous changes in user requirements and runtime environments. In this paper we propose an autonomic computing approach to the problem of reconfiguration, that is, enabling the service based system to configure itself by means of a loop of monitoring, analyzing, planning and executing actions. We begin by formalizing the definition of configuration and reconfiguration. Then, we describe how we implemented the autonomic computing mechanisms for reconfiguring service-based systems to satisfy Service Level Agreements with minimal resource consumption. The approach is demonstrated on a resilient service provisioning environment. Finally, the preliminary experiments are evaluated to determine the effectiveness of proposed approach. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.103">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Service chaining, the act of stringing a sequence of services together to form a new service, is a key element of web services. However, for web services to reach its full potential the issue of testing service- chaining at the network level must be resolved. How can one map the micro-level service-service interactions to the macro-level system performance? For instance, as service chains become longer and more complex, how do they affect end-user quality of service? Focusing on aggregate service chains.situations in which the user invokes a service that carries out the chain, without the user being aware of the individual services.we tackle these questions using a Java simulation tool to model service chaining, visualize network traffic and quantify service chain complexity. We demonstrate that one can orchestrate very complex service chains in a simple distributed manner and quantify how service chain complexity affects end-user quality of service and network loading. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.82">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=243</link>
<description><![CDATA[Automatic or assisted workflow composition is a field of intense research for applications to the world wide web or to business process modeling. Workflow composition is traditionally addressed in various ways, generally via theorem proving techniques. The originality of this research stems from the observation that building a composite workflow bears strong relationships with finite model search, and that some workflow languages can be defined as constrained object metamodels [1], [2]. This leads to consider the viability of applying configuration techniques to this problem. Our main contribution is to prove the feasibility of such an approach, with some advantages and drawbacks compared to logical based techniques. We present a constrained object model for workflow composition, based upon a metamodel for workflows and ontologies for processes and data flows. Experimental results are listed for a working implementation that generates complex interleaving composite workflows involving transformations, synchronization and branching constructs. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.38">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[In this paper we propose a technique for the automated synthesis of new composite web services. Given a set of abstract BPEL4WS descriptions of component services, and a composition requirement, we automatically generate an executable BPEL4WS process that, once deployed, is able to interact with the components to satisfy the requirement. We implement the proposed approach exploiting efficient synthesis techniques, and experiment with some case studies taken from real world applications and with a parameterized domain. We show that the technique can scale up to cases in which the manual development of BPEL4WS composite services is not trivial and is time consuming. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.27">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=245</link>
<description><![CDATA[The semantic web promises automated invocation, discovery, and composition of web services by enhancing services with semantic descriptions. One such language used for creating semantic descriptions is the Web Ontology Language or OWL. An upper ontology for web services called OWL-S has been created to provide a mechanism for describing service semantics in a standard, well-defined manner. Unfortunately, the learning curve for semantic-rich description languages such as OWL-S can be steep, especially with given the current state of tool support for the language. This paper describes an automated software tool that uses model-driven architecture (MDA) techniques to generate an OWL-S description of a web service from a UML model. This allows the developer to focus on creating a model of the web service in a standard UML tool, leveraging existing knowledge. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.9">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Web Services offer an interoperability model that abstracts from the idiosyncrasies of specific implementations; they were introduced to address the increasing need for seamless interoperability between systems in the Business-to-Business domain. We analyse the require- ments from this domain and show that to fully address interoperability demands we need to make use of semantic descriptions of Web Services. We therefore introduce the Web Service Execution Environment (WSMX), a software system that enables the creation and execution of Semantic Web Services based on the Web Service Modelling Ontology. Providers can use it to register and offer their services and requesters can use it to dynamically discover and invoke relevant services. WSMX allows a requester to discover, mediate and invoke Web Services in order to carry out its tasks, based on services available on the Internet. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.139">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[The semantic Web and Web services technologies have provided both new possibilities and challenges to automatic information processing. There are a lot of researches on applying these new technologies to current personal Web information retrieval systems, but no research addresses the semantic issues from the whole life cycle and architecture point of view. Web services provide a new way for accessing Web resources, but until now, they have been managed separately from conventional Web contents resources. In this paper, we point out new system requirements and propose a conceptual architecture for a personal semantic Web information retrieval system. It incorporates semantic Web, Web services and multi-agent technologies to enable not only precise location of Web resources but also the automatic or semi-automatic integration of hybrid Web contents and Web service resources. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.23">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=248</link>
<description><![CDATA[Service Oriented Architectures (SOA) are becoming the prevalent approach for realizing modern services and systems. SOA offers superior support for autonomy (decoupling) and heterogeneity compared to previous generation middleware systems, resulting in more scalable and adaptive solutions. However, SOA have not adequately addressed management, while traditional management solutions do not sufficiently scale to address the needs of (global) Web services. We propose scalable management based on models and industry standards. We discuss a use case for global service management, we present its design, implementation and preliminary evaluation. We retain all the benefits of SOA while also enabling global scale manageability. Our approach provides manageability that is comprehensible for administrators yet automated enough for integration into autonomous systems. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.45">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=249</link>
<description><![CDATA[Web Service provides a means to integrate functional components and for business IT solutions in an enterprise or cross-enterprise environment. Enterprise resources are consumed by Web Services to provide desired capabilities expected by the users. However, beyond service provisioning, an enterprise needs to manage their Web services and related resources in an optimal manner in order to maximize the resource usage. This paper presents a framework of Web service management aimed for solving the resource allocation issues based on System Dynamics models. Our approach combines the business operational consideration and IT infrastructure configuration. Dependency that is derived from impact analysis of different perspectives is an essential part of the model and can be built into control system. The resultant system embodies the capability of autonomic Web service management to certain degree if not fully. The reference architecture of this framework is accounted in this paper. We also demonstrate dynamical behavior of the system through simulation. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.131">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[As Web services start to be deployed for mission critical applications and for e-Business scenarios, higher Quality of Service (QoS) and continuous service delivery become a critical issue to ensure high availability and reliability in spite of the failure or unavailability of the participating services or networks. These challenges call for vast improvements in the Web services containers and the mediation infrastructure. To address these requirements, we propose Web Services Message Bus (wsBus), a lightweight service-oriented middleware for reliable and fault tolerant Web services interactions. This paper first discusses wsBus architecture and features and then it reports some experimental results to illustrate the effectiveness of wsBus in adding reliable and uninterrupted services to a supply chain management system. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.3">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[With the realisation of the potential benefits of business process automation, many standards, best practices and technologies have evolved to model and execute business processes. The emerging web services technology provides great flexibility for the development of cross platform, service oriented applications. This paper addresses the utilisation of the web services technology for business process enactment and discusses a standardised architecture for web service based business process execution. As a key objective it highlights the need for standardisation in web service based business processes execution. In elaborating on the above need, this paper defines the development of a standard architecture to address key concerns such as service invocation, integration, transaction manage- ment, security and resource management in using the web services technology for business process execution. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.56">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=252</link>
<description><![CDATA[There is a growing demand for provisioning of proportional responsive- ness differentiation to various clients on scalable Web servers to meet changing resource availability and to satisfy different client requirements. Theoretically, a queueing-based processing rate allocation scheme is able to achieve the objective by providing different processing rates to requests of different client classes. However, in this paper, we find that an implement- ation of the queueingtheoretical scheme shows weak proportionality with large variance because it does not have fine-grained control over the consumption of resources that the kernel consumes and hence the processing rate is not strictly proportional to the number of processes allocated. We design a feedback controller and integrate it with the queueing theoretical scheme. The integrated application-level approach allocates a certain number of processes to handle requests of different client classes according to the queueing-theoretical scheme. The process allocations are then adjusted according to the difference between the target response time and the achieved response time by using the proportional integral derivative control. Results demonstrate that this integrated approach can enable Web servers to provide fine-grained response time differentiation. The approach is robust and can be practically deployed on Apache Web servers. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.15">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[The web service paradigm promotes the delivery of software as a service via the web, instead of a product to end-users. The increase in assigned responsibilities for supporting organizational operations drives the needs for higher operational efficiencies (i.e. performance and reliability) and flexibilities (i.e. customizations). This paper makes two contributions. An infrastructure to support the development and operation of customized cost model components, used to manage cost efficiency and reliability issues. Secondly, a generic cost model algorithm that can be used as the foundation algorithm for cost model components. Further, the process of web service relocation is also demonstrated and implementation has also been discussed. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.5">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[In this paper, we introduce Web Service Application Session Services, WS-Session, for Web service based application session management in communication. A two-way Web service framework is described. It supports the use of Web service in the situation of telecommunication where the communication endpoint can be both a client and a peer-to-peer server. We describe the interface design in two-way Web service interaction based on the concept of tightly coupled interface and loosely coupled interface solutions. The proposed approach provides full support of asynchronous outbound operations and event notifications in communication services. It is implemented in a research prototype system that provides both standard based (ECMA-348) services and Avaya service extensions. In addition, we investigated the integration of our proposed approach with BPEL4WS. It allows the user to create new services through a drag-n-drop based service creation environment (ECLIPSE/BPEL4WS). It leads to a paradigm of service creation through Web service composition. More sophisticated telecommunication services are created from composing the basic services. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.130">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Presence technology conveys the willingness and ability of an entity to communicate and is very useful in developing innovative applications. Protocols and APIs have been proposed for presence, but these APIs are at a low level of abstraction. Web services provide the flexibility to develop loosely coupled applications with coarse-grained interfaces. This paper proposes a novel Web service for presence application development. This Web service is presence protocol independent and its use is illustrated in the paper by a concrete application. We have implemented it as a gateway towards an IETF SIMPLE based presence server, but other implementations are possible. The mapping is discussed and the prototype described. Performance measurements are also made. The results indicate that the additional overhead introduced because of XML-based SOAP messages is not prohibitive, although significant. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.12">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=256</link>
<description><![CDATA[The benefits provided by Web Service protocols are well recognized. Deployments to date, however, have concentrated on new applications, and existing Web-based applications. A host of legacy applications and protocols continue to exist in their native forms, outdated, yet entrenched due to large installed bases. This paper details our observations in integrating a Web Service infrastructure into the Simple Network Management Protocol (SNMP). SNMP has been in use for over a decade and a half, predominantly in network equipment embedded systems. Our Web Servicebased approach allows us to enhance our existing application with XML/SOAP interoperability, SSL/TLS security, and the potential to migrate both application and protocol layers to encompass future extensions and Web browser accessibility. The difficulty with SNMP, and many other legacy networking protocols, is that much of the extensive installed base is hosted on limited capability, legacy hardware. While the benefits of our scheme are quite tangible, the performance impact of adding these features is not well known. We examine two approaches, an integrated solution using a light-weight HTTP/SOAP stack, as well as a standard Java Web server implementation. Our tests reveal unanticipated performance results through both the integrated and proxy methods. We discuss the impact of these anomalies on the viability of our approach and address the broad issue of migrating Web Services to legacy embedded architectures. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.91">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=259</link>
<description><![CDATA[An increasing amount of Web services are being implemented using process management tools and languages (BPML, BPEL, etc.). The main advantage of processes is that designers can express complex business conversations at a high level of abstraction, even reusing standardized business protocols. The downside is that the infrastructure behind the Web service becomes more complex. This is particularly critical for Web services that may be subjected to high variability in demand and suffer from unpredictable peaks of heavy load. In this paper we present a flexible architecture for process execution that has been designed to support autonomic scalability. The system runs on a cluster of computers and reacts to workload variations by altering its configuration in order to optimally use the available resources. Such changes happen automatically and without any human intervention. This feature completely removes the need for the manual monitoring and reconfiguration of the system, which in practice is a difficult and time-consuming operation. In the paper we describe the architecture of the system and present an extensive performance evaluation of its autonomic capabilities. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.28">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=260</link>
<description><![CDATA[Web service is an internet-based software component that can shield all sorts of resources on basis of standard protocol stack. It helps to raise the level of abstraction and simplify conventional COTS middleware for resource sharing and cooperation across organization. In this paper, a Web service container framework (WSCF) is presented to offer an effective systematic solution for Web service-based application supporting environment, referencing from CORBA and J2EE system managing architecture and using SOAP interoperation protocol. The proposed framework focuses on addressing problems in two aspects: 1) Web service runtime supporting technologies: unified resource mapping strategy, flexible service adaptation mechanism, and SOAP engine scheduling algorithm; 2) several application supporting services: publication and discovery service, Web service composition service, and security service, etc. In particular, it describes ongoing project StarWebService that has followed WSCF. Finally, some open issues about WSCF are introduced and the future direction of WSCF is pointed out. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.137">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Web services are software systems designed to support interoperable machine-to-machine interaction over a network. WSDL descriptions, often characterized as IDLs for Web services, are a key for Web service interoperability. Therefore, special care should be taken in designing WSDL descriptions. We present an approach that provides UML-based support to design and validate WSDL descriptions. To promote Web service interoperability, WS -I organization provides a Basic Profile that defines clarifications, refinements, interpretations and amplifications of Web service specifications, including WSDL. We propose UML-based profiles to define structural rules of WSDL documents as well as Basic Profile recommendations for WSDL descriptions. These profiles can be used to guide the user in designing correct and Basic Profile compliant WSDL descriptions and to check the validity of existing WSDL descriptions. We propose a method and tools for such validity checking, and demonstrate the applicability of the approach with a case study. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.125">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[The growing popularity of Service Oriented Computing based on Web services standards is creating a need for paradigms to represent and design business processes. Significant work has been done in the representation aspects with regards to WSBPEL. However, design and modeling of business processes is still an open issue. In this paper, we present a novel designer for business processes, which allows for intuitive modeling of Web processes, as well as using a template based approach for semi-automatically integrating partners either at design time or at deployment time. This work has been done as part of the METEOR-S project, which concentrates on adding semantics to the entire Web process lifecycle. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.16">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=263</link>
<description><![CDATA[The ultimate goal of the Semantic Web is to enable automated collaboration over the Internet, based on ontologies as semantic terminology definitions and Web Services as computational facilities accessible over the Web. An essential functionality for collaboration support on the Semantic Web is detection of entities, services, and other resources that are to be used for achieving a successful collaboration. This is commonly referred to as discovery, wherefore the emerging concept of Semantic Web Services promises more effective support than conventional Web Service technologies: based on exhaustive semantic description frameworks, intelligent mechanisms are envisioned for discovery, composition, and contracting of Web Services. This paper outlines an approach for automated collaboration support using Semantic Web Services, and presents the realization of semantically driven discovery of cooperation partners and usable Web Services as a main component for collaboration establishment.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.90">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[This paper presents DynaBot, a domain-specific web service discovery system. The core idea of the DynaBot service discovery system is to use domain-specific service class descriptions powered by an intelligent Deep Web crawler. In contrast to current registry- based service discovery systems -- like the several available UDDI registries -- DynaBot promotes focused crawling of the Deep Web of services and discovers candidate services that are relevant to the domain of interest. It uses intelligent filtering algorithms to match services found by focused crawling with the domain-specific service class descriptions. We demonstrate the capability of DynaBot through the BLAST scenario and describe our initial experience with DynaBot. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.49">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=265</link>
<description><![CDATA[Future web applications will be more collaborative and will use the standard and ubiquitous Internet protocols. We have previously developed System on Mobile Devices (SyD) middleware to rapidly develop and deploy collaborative applications over heterogeneous and possibly mobile devices hosting web objects. In this paper, we present the software engineering methodology for developing SyD- enabled web applications and illustrate it through a case study on a System of Calendar application, with implementation on iPAQs and its performance metrics study. SyD-enabled web objects allow us to create a collaborative application rapidly with limited coding. In this case study, the modular software architecture allowed us to hide the inherent heterogeneity among devices, data stores, and networks by presenting a uniform and persistent object view of mobile calendar objects interacting through XML/SOAP requests and responses. The performance results we obtained show that the application scales well as we increase the group size and adapts well within the constraints of mobile devices. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.7">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[In a distributed web service integration environment, the selection of web services should be based on their reputation and quality-of- service (QoS). Various trust models for web services have been proposed to evaluate the reputation of web services/service providers. Current mechanisms are based on tracing the feedbacks to the past behaviors of web services. However, very few of them consider the robustness and attackresiliency of the trust models. In this paper, we present an attack resilient distributed trust management system in a web service management environment. The proposed attack resilient trust model uses two vectors to capture the behavior and the trustworthiness of a web service/service provider based on our analysis on the possible attacks against the trust models. We also present a set of experiments that show the effectiveness of our trust model in detecting malicious behavior of service providers.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.99">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=267</link>
<description><![CDATA[Actually Internet applications can provide not only information, but also, another way of getting distributed computing. Cooperative information systems are autonomous and heterogeneous systems, distributed geographically, but interconnected. Web Services provides a set of interoperable standards that can be used to connect distributed applications. On this environment, security is a critical issue, and an attack can expose systems services without authentication. An end-to-end connection, like the ones involved in such systems, usually requires that an authentication can be shared between different information systems. Web Services security model is not yet fully defined and a lot of proposals are emerging, delaying the adoption of this technology in many situations. In this paper we present multiplatform authentication control system based on an extension of SRP protocol, using SAML. Within this solution, authentication control can be leveraged, even with weak passwords and an authentication assertion can be exchanged with different cooperative information systems. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.21">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=269</link>
<description><![CDATA[In this paper, we introduce a theoretical framework for two-way Web service (WS) interaction and interface design based on the concepts of operation reversal and XML type generalization. Under this theoretical framework, two generic types of interface solutions in two-way WS interaction, i.e. tightly coupled (TC) interface and loosely coupled (LC) interface, are formally defined and studied. The proposed theoretical framework is used to design, derive and verify WS interface for full duplex two-way WS interaction. An algorithm of interface verification is described that allows effective WS interface design and verification to support asynchronous two-way WS operation and event notification. The interface verification algorithm in our approach utilizes verification by derivation and verification by content to validate the client interface in two-way WS interaction. Use case studies are performed for both TC and LC interface solutions. A generic infrastructure based on two-way Web service application proxy (2SAP) is described and implemented. The proposed approach is applied to applications of realizing ECMA-348 for WS enablement of telecommunication.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.124"> buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[The many conflicting technical, organizational, legal and domain-level constraints make the implementation of secure, inter-organizational workflows a very complex task, which is bound to low-level technical knowledge and error prone. The SECTINO project provides a framework for the realization and the high-level management of security-critical workflows based on the paradigm of Model Driven Security. In our case the models are translated into runtime artefacts that configure a target reference architecture based on web services technologies. In this paper we focus on the Global Workflow Model, which captures the message exchange protocol between partners cooperating in a distributed environments well as basic security patterns. We show how the model maps to workflow and security components of the hosting environments at the partner nodes. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.83">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=271</link>
<description><![CDATA[Service-oriented architecture is emerging as a compelling paradigm for developing web-based software applications. In this style, the functional components of the system are implemented in various programming languages as network-accessible "services" declaratively specified (in WSDL) and declaratively composed in workflows (using BPEL4WS). Despite this fundamentally distributed conceptualization of service composition, most current middleware assumes that the specification of the service composition is interpreted at run time by a central middleware node. This implies inflexible composition evolution: all parties must be updated concurrently to avoid interaction failures. This paper introduces an intelligent-agent framework that wraps web services in a conversation layer and is capable of a simple workflowadaptation function. The conversation layer implements protocols and consults globally shared, declarative policy specifications to resolve conversation failures. Two case studies illustrate this approach. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.116">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=272</link>
<description><![CDATA[This paper describes a scalable approach to the enabling of legacy scientific applications on computing Grids using a service- oriented architecture. In the context of this paper Grid enabling means turning an existing application, installed on a Grid resource, into a service and generating the application-specific user interfaces to use that application through a web portal. Scalability is achieved by providing a common abstraction for a category of applications and providing a "generic" application service to wrap those applications as services. The focus of this paper’s approach is on Grid-enabling "command-oriented" scientific applications. The novel aspect of the approach is that the entire process - from turning an application into a service to the user-interface generation for that application - is done automatically, without requiring coding or Grid-system downtime. Portlet technology is used to dynamically generate application-specific interfaces. Further, the approach makes it possible to customize the applications for different user groups by way of simplifying, restricting or composing the functionalities of applications. The approach is useful for building Grid portals on which a large number of applications need to be dynamically enabled. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.17">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=273</link>
<description><![CDATA[For companies and government agencies alike, the emergence of Web services technologies and the evolution of distributed systems toward Service Oriented Architectures (SOA) have helped promote collaboration and information sharing by breaking down "stove-piped" systems and connecting them via loosely coupled, interoperable system-to-system interfaces. Such architectures, however, also bring about their own security challenges that require due consideration. Unfortunately, the current information security mechanisms are insufficient to address thesechallenges. In particular, the access control models today are mostly static and coarsely grained; they are not well-suited for the service-oriented environments where information access is dynamic and ad-hoc in nature. This paper outlines the access control challenges for Web services and SOA, and proposes an Attribute Based Access Control (ABAC) model as a new approach, which is based on subject, object, and environment attributes and supports both mandatory and discretionary access control needs. The paper describes the ABAC model in terms of its authorization architecture and policy formulation, and makes a detailed comparison between ABAC and traditional role-based models, which clearly shows the advantages of ABAC. The paper then describes how this new model can be applied to securing web service invocations, with an implementation based on standard protocols and open-source tools. The paper concludes with a summary of the ABAC model’s benefits and some future directions.  <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.25">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Though 20 years have passed since the birth of CSCW, the original goal of it is not reached as well as people expected. This situation is mostly due to the supporting technology especially the infrastructure. Today, great changes have taken place in technology, including Grid computing and Web services. These technologies, we think, will significantly affect the application of CSCW. In this paper, a framework called CoFrame is proposed to answer the challenges faced by CSCW. Based on the emerging Grid and Web service technologies, CoFrame provides some general yet flexible cooperation related services and organizes them into different layers. The elaborately designed services and architecture make CoFrame adaptive to diverse requirements of different domains. The paper details the framework and demonstrates its application with a case study in e-learning. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.33">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[The poor performance of WS-Security (WSS) processing is often a topic of concern and prevents its wider adoption. We focused on byte-level similarities in WSS messages and implemented a template-based WSS processor. Inside the processor an automaton is employed that matches the incoming messages and extracts signature values and/or encrypted values. WSS operations including XML Canonicalization are performed against the extracted values, without costly XML parsing and traversal. This is more than twice as fast as the DOM-based WSS processor and our prior work with a stream-based processor. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.70">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=278</link>
<description><![CDATA[Policies provide flexible grammar to describe the capabilities, requirements and general characteristics. In loosely-coupled web services domain, policy has been considered as a possible mechanism to describe the characteristics of services, associate and evolve with these services dynamically. However there lacks a systematic framework to take into account the employment of policies in web services as a whole. In this paper, based on the lifecycle of policies, a general policy framework for web services is proposed, including policy generation, enforcement, publication, negotiation and evolution. In different modules of the framework, a set of mechanisms and tools are discussed and presented. At the end of the paper, a policy enabled telecom open service delivery platform is presented. Telecom operators open their network capabilities through deploying their services as web services on the platform, following Parlay X Web Services specification. Third- party value added service providers use WSDL and policies to access services.

<description><![CDATA[In this paper we present a web services-based platform that facilitates and speeds up the development and deployment of context-aware, integrated mobile speech and data applications. The platform is capable of handling different types of context and offers sophisticated personalization mechanisms. To illustrate the usefulness of the platform and to validate the claim that cross-platform application development, in particular mobile, context-aware applications, is easier and faster with web services technologies, we present a demonstration application. It serves tourists with interesting information and services in their specific context, and contributes to the achievement of their current goals. Finally, we present a number of problems that we experienced in the implementation process as well as the feedback that we received from real users who tested our application. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.106">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=282</link>
<description><![CDATA[In this paper we propose a solution for optimizing (web service) business workflow response times through dynamic resource allocation. On-the-fly monitoring is combined with a novel workflow modeling algorithm that discovers critical execution paths and builds "dynamic" stochastic models in the associated "critical graph." One novel contribution of this work is the ability to naturally handle parallel workflow execution paths. This is essential in applications where workflows include multiple concurrent service calls/paths that need to be "joined" at a later point in time. We discuss the automatic deployment of on-the-fly monitoring mechanisms within the resource management mechanisms. We implement, deploy and experiment with a proof of concept within a generalized web services business process (BPEL4WS/SOAP) framework. In the experimental setup we explore and show the natural adaptation to changing workflow conditions and appropriate automatic re-allocation of resources to reduce execution times.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.50"> buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[While a streaming-XPath engine provides a more efficient XPath evaluation performance than a DOM based engine, it still requires time to parse a whole XML document at least once. Taking into consideration that XPath is used to extract data from Web Service messages, the target element may be in the first part of documents, such as the SOAP Headers. Therefore, it is wasteful to parse a document all the way to the end. We present a new XPath engine named "XScope," which eliminates parsing XML documents by Schema information. In this paper, we describe the XScope approach, then evaluate its performance and show that the engine works effectively in Web Services. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.101">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[The response time of SOAP invocation over Http is an important designing factor and evaluating metric for Qos and web services related computing. This paper presents a novel model to compute response time of SOAP over Http/1.1. It takes several influencing parameters into account, including compression methods, maximum segment size, round trip time, initial value of time-out sequence, the number of packets per ACK, maximum congestion control window size and packet loss rate. How to set these parameters to compute the response time of SOAP over Http/1.1 is illustrated and the model is validated with TPC-H benchmark based simulation data. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.81">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[The growing need for enterprises to have instantaneous access and visibility to data is fuelling the need for enterprise data integration. An enterprise having fragmented systems on varied technologies is a very commonly occurring scenario. In this paper we take a business case scenario with heterogeneous systems and describe a non- intrusive service oriented approach for achieving enterprise wide data integration. We take a holistic view of the problem statement and propose an end to end architectural approach that encompasses the ETL activities to the shared data access layer. This meta-data based architecture is highly extensible requiring minimal change in existing applications and business process yet adhering to the long term architectural strategy. We also propose the creation of fine grained shared business services which are supported by underlying shared data services. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.112">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[With the Semantic Web and Web Services we have potential technologies to develop architectures that support the broad integration of business processes. A growing number of standards like BPEL1 or WSCI2 enable us to develop integrated business process architectures on a corporate as well as on an industrywide level. Service-oriented architectures (SOA) permit us to develop new generations of integrated business applications from reusable components and along structures that represent mundane as well as sophisticated business processes. However, experiences in business process modeling show that developing Web services and the corresponding orchestration layer is quite challenging. The coexistence of Semantic Web standards and natural language could help to lower the language barrier in design and orchestration, allowing even non-tech people to be involved in application design. Translating natural language descriptions into the semantics of the respective SOA can help to facilitate and fasten the design process.  <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.67">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Web ontologies as the foundation of the Semantic Web were proposed to solve the problem of integrating and sharing heterogeneous information resources in the Web. Massive amount of domain specific ontologies have been constructed and published in different domains on the Web. However, several limitations make existent ontologies not suitable for high-level and large-scale applications. In this paper, we described a context-based ontology service with a large-scale Traditional Chinese Medicine (TCM) ontology, which provides clients with an interactive interface and intelligent inter-operations to assist users in sharing and exploiting large-scale TCM information and can be used as a semantic view for domain specific problem solving. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.39">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[We address the problem of 3D medical volume reconstruction using web services. The use of proposed web services is motivated by the fact that the problem of 3D medical volume reconstruction requires significant computer resources and human expertise in medical and computer science areas. Web services were implemented as an additional layer to a dataflow framework called Data to Knowledge. In the collaboration between UIC and NCSA, pre-processed input images at NCSA were made accessible to medical collaborators for registration. Every time medical collaborators inspected images and selected corresponding features for registration, the web server at NCSA was contacted and the registration processing query was executed using the Image to Knowledge library of registration methods. Co- registered frames were returned for verification by medical collaborators in a new window. This paper presents 3D volume reconstruction problem requirements, architecture of the developed prototype system and the tradeoffs of our system design. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.1">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=289</link>
<description><![CDATA[Quality of Services (QoS) management in compositions of services requires careful consideration of QoS characteristics of the services and effective QoS management in their execution. A Web service is a software system that supports interoperable application-to- application interaction over the Internet. Web services are based on a set of XML standards such as Simple Object Access Protocol (SOAP). The interactions of SOAP messages between Web services form the theoretical model of SOAP Message Exchange Patterns (MEP). Web Services Business Process Execution Language (WSBPEL) defines an interoperable integration model that facilitates automated process integration in intra- and inter-corporate environments. A service-level agreement (SLA) is a formal contract between a Web services requestor and provider guaranteeing quantifiable issues at defined levels only through mutual concessions. Based on a prior research work on Message Detail Record (MDR), this paper further proposes a SOAP message tracking model for supporting QoS end-to-end management in the context of WSBPEL and SLA. This paper motivates the study of QoS management in a Web service composition framework with the evolution of a distributed toolkit in an industrial setting. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.19">buy it!</a><div></div><div></div>]]></description>

<description><![CDATA[We recently developed "System on Mobile Devices"(SyD) middleware for rapidly developing and deploying collaborative distributed applications over a collection of autonomous web objects and data-stores, independent of the underlying device, data, or network. SyDListener is a key component of SyD middleware. SyDListener provides a set of interfaces and classes that allows distributed SyD-based application components to communicate seamlessly in mobile environments. SyDListener provides a uniform object view of the underlying server application and enables client applications to remotely invoke those methods using XML messages. SyDListener is implemented as a multi-threaded wrapper with simple persistence management and asynchronous invocation functionality for J2ME Mobile Information Device Profile (MIDP) on Connected Limited Device Configuration (CLDL) devices. We discuss the functionality, architecture, implementation, and performance of SyDListener. We believe it is the first comprehensive working prototype of its kind for Java enabled handhelds with a small footprint of 10 KB. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.18">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[In a short period the Web has become an important part of our lives. However, the full potential of the web is still not realized. Two recent developments--web services and the semantic web--are steps in the direction of utilizing the full potential of the Web. Web services allow applications to utilize the web for automatically extracting (and updating) information while the semantic web enterprise promises to provide the infrastructure that allows intelligent web services to be rapidly created and deployed. However, with this comes the task of transforming the traditional web-based systems to web-services over the semantic web. In this paper, we demonstrate how an existing successful web-based system for providing help to first responders of chemically hazardous emergencies (called E-plan) can be converted into a web-services based model using the semantic web and intelligent reasoning technologies. Our efforts can be regarded as a case study in converting monolithic web-based applications to a more agile, rapidly deployable intelligent web-services model. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.122">buy now!</a><div></div><div></div>]]></description>

The purpose of this work is to break the strong ties between programming languages and runtime environments and thus make it possible to innovate at both ends independently. While this goal has been pursued in previous work, the specific focus of this work is on Web Services and Service-Oriented Architectures (SOAs); focusing on this domain and its particular properties makes it possible to achieve this goal with affordable efforts. The key idea is to introduce a Service Language Layer (SLL) which gives a high-level abstraction of a service-oriented program and which can easily and efficiently be executed on alternative Web Services platforms. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.113">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[IT service providers use applications to support their business processes. The need for specialized IT management functionality and information generates a multitude and diversity of management applications that can be recognized in one IT provider’s scenario. To run IT and to provide IT services effectively and efficiently, management applications have to be integrated along operational processes. This article introduces an approach to integrate management applications by leveraging a Service-oriented Architecture (SOA). Therefore, a sufficient understanding of IT service provider’s processes and cooperative roles is essential. The presented SOA defines how to integrate management applications.  <a href="http://csdl.computer.org/comp/proceedings/icws/2005/2409/00/24090785.pdf">Full Article Text</a> <strong>DOI Bookmark: </strong>http://doi.ieeecomputersociety.org/10.1109/ICWS.2005.114<div></div><div></div>]]></description>

<description><![CDATA[The benefits of connecting businesses through Web-services- based trading exchanges are huge. These exchanges allow various companies to connect supply chains in various industries or across industries, introducing new efficiencies and ways of buying, selling, and brokering products and services. Connecting businesses through Web-services-based trading exchanges give companies the ability to transact in ways that were never before possible. These exchanges help connect buyers to sellers and provide a shorter procurement trading lifecycle. Having this account, in this work a business processes integration and monitoring system has been developed to automate, integrate and monitor many of the enterprise business processes described as Web services without recurring to large investments in software development and deployment. The contribution of this work consists in a service-oriented architecture that follows the SOA’s principles of improving economical benefits of business collaborations. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/icws/&amp;toc=comp/proceedings/icws/2005/2409/00/2409toc.xml&amp;DOI=10.1109/ICWS.2005.32">buy now</a><div></div><div></div>]]></description>

Widely adopted, distributor-based systems forward client requests to a balanced set of backend servers in complete transparency to the clients. In this paper, we use power and locality-based request distribution at the distributor to provide optimum power conservation, while maintaining the required QoS of the system. The distribution scheme uses a simple memory management technique using pinned memory on the backend servers and proactive distribution, with the aid of data organization of the website, to improve the locality of the files. A simple on-off based power management scheme is applied to conserve power. Our scheme provides reduced response time to the clients and improved power conservation at the backend server cluster without compromising performance. Simulations involving real-time web traces and latest web technologies witness performance boost of 15-23% and power conservation of 15-48% over the existing policies.

<description><![CDATA[The rapid advance of technologies like Web services enables solutions to exploit more and more of the potential of the Web in many ways, recently especially in the field of federating distributed systems within or between businesses. To sustain maintainability and cope with the evolving application life cycles, a global uniform view on all involved sub systems and underlying infrastructure is required. This can be provided by a model that serves as a map for the landscape of the overall system to act as a guide to evolution. In this paper, we introduce the i2Map as an approach to these modeling demands focused on federable Web-service-based applications.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=758</link>
<description><![CDATA[Scientific (e.g. genetic) data and relative processing tools are usually located at different websites; scientists have been strongly expecting a universal solution to compare, integrate, and analyze these heterogeneous and usually large size data with processing tools from distant sites for years. This paper will present a pipelined web services workflow framework: SPL (Service Pipeline Logic) that can reduce frequent data interaction between sites and mitigate network traffic incurred by huge scientific data transmission during the course of processing a bioinformatics workflow. The paper shows that the processing time of a complex bioinformatics workflow can be saved remarkably with the application of SPL.

<description><![CDATA[The objective of this research is to seek the exact nature of how an organization should apply a serviceoriented design to systems that were previously standalone heterogeneous applications. For this objective, three applications are developed and integrated by using a service-oriented architecture: a biometric attendance system, a surveillance system, and a point of sale system. Each application is classified by a combination of two properties: input or output heavy application, local or remote running application. Based upon the combination, two types of service-oriented integration approach, fully or partially web serviced integration, are suggested according to the extent of the usage of web services. Based upon the experiences gained from developing the three applications, the guidelines for adopting web services are proposed when an organization is integrating applications.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=868</link>
<description><![CDATA[When a composition of Web services is designed, available services are put together to form a defined flow of executions. In a discovery process, a trader proposes available Web services as potential candidates. In a succeeding selection, for each task a trader chooses one candidate to form the optimal composition due to selection criteria. This paper discusses how the selection can consider different Quality-of-Service (QoS) categories to determine the most suitable candidates for the composition. If more than one category is used for optimisation, a multi-dimensional optimisation problem arises. This mentions similarities to similar combinatorial problems. Then, possible solutions are proposed and their performance is evaluated.

<description><![CDATA[In Service Oriented Architectures, complex applications are composed from a variety of functionally equivalent Web services which may differ for quality parameters. Under this scenario, applications are defined as high level business processes and service composition can be implemented dynamically by identifying the best set of services available at run time. In this paper, we model the service composition problem as a mixed integer linear problem where both local constraints and global constraints can be specified.

<description><![CDATA[The lack of effective trust establishment mechanisms for web services impedes the deployment of trust models for online services. One important issue is the lack of privacy protection in trust establishment. Current web service technology encourages a client to reveal all its attributes in a standard credential to the service provider for trust establishment. We propose a mechanism whereby the client formulates a single trust primitive by associating a subset of required attributes in a standard credential to negotiate a trust relationship. Client privacy is preserved because only those required attributes are revealed. After negotiation, a trust group element with dynamic validation is used to represent this trust relationship.

<description><![CDATA[We envision users discovering suitable web objects and configuring them on-the-fly with their desired high-level application logic, with the programming and deployment carried out entirely on the web. Easy configurability and interplay of web entities implies evolution of a few common sense, yet powerful set of core primitives for effective coordination, akin in simplicity and strength to the HTTP protocol. Current web services technology lacks Infrastructure support, theoretical sound fundamental framework for web services coordination and composition, and easy use tools for web application development. Our Web Coordination Bond system gears towards finding solutions to afore- mentioned research challenges. We have proposed web coordination bonds as a potential candidate for a set of core artifacts for web service coordination/choreography [2]. Section 2 illustrates the ideas of web coordination bonds. Section 3 introduces the concept of Web Process Architecture, which is a simple but powerful enhancement to the web services infrastructure that makes web services stateful, coordination and transaction aware capable enteritis. Section 4 describes our BondFlow [5] system, which is a development and deployment platform for collaborative distributed applications over web objects including web services.<a href="http://csdl.computer.org/comp/proceedings/icws/2005/2409/00/24090819.pdf">Full Article Text</a>

<description><![CDATA[Recent advances in the distributed computing infrastructure like Web, Grid, and Pervasive computing environment accompany demands for a more powerful and autonomous service framework. We believe it is feasible to achieve service discovery and matching in an automated manner and perform the service execution not in restricted environments. For the purpose, we developed an autonomous service framework, called ASF, which allows autonomous service to be published, discovered and executed in distributed environments based on the autonomous service specification, extension of the Web Service Ontology (OWL-S) to incorporate physical/logical resources and resource policy.? ?

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=893</link>
<description><![CDATA[? As the increasing development of application technology and infrastructure, many kinds of application and resources can be encapsulated as web service and its variations, and service-oriented computing become research hot. But, we believe service-oriented computing should establish on virtualized service rather than concrete service instance directly. In this paper, we present formalized model of virtualized service and service instance, and define the concept of service virtualization. Then, we propose the implementation solution of virtualized service- oriented application from perspective of global and local instantiation process. <a href="http://csdl.computer.org/comp/proceedings/icws/2005/2409/00/24090835.pdf">Full Article Text</a>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=896</link>
<description><![CDATA[This research proposes to modernize a legacy software system by using web services as the main building blocks of the software reengineering. For this purpose, a legacy theorem proof checking and derivation tool called Bertie3 is reengineered in terms of service-oriented architecture, service-oriented componentization, and external data representation and serialization. With the web services of derivation checking engines and first-order markup languages, a minimal amount of development time can be spent working on well-known and well-developed components. More time can be spent updating the features that make the tool unique. This case study shows that modernizing a software system with web services will allow the business components of the system to be easily expanded and integrated with other application components for future demands.? ?

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=899</link>
<description><![CDATA[Nowadays, technologies involved in Web information distribution services are evolving to adapt themselves to new user requirements. Usually, these new technologies are used separately. ELIN (Electronic Newspaper Initiative) project is an European Commission funded project, that tries to integrate the newest standards and technologies involved in multimedia delivery applied to web newspapers. It has as objective the delivery of any type of media format to any kind of user terminal in an efficient way. In order to do that, it takes the approach of using MPEG standards: MPEG-4 for video delivery, MPEG-7 for data classification and MPEG-21 for data management and adaptation. So it integrates the totality of solutions provided for the MPEG group.? ?

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=902</link>
<description><![CDATA[In this paper, we develop a web service for ontology comparison based on a novel senses refinement algorithm, which builds senses sets to represent the semantics of the input ontologies. The senses refinement algorithm converts the measurement of ontology difference into simple set operations based on set theory, thus ensures the efficiency and accuracy of the ontology comparison. We believe our web service is the first available online measurement tool for ontology comparison.? ?
