<item><title><![CDATA[Multiversion Concurrency Control for Large-Scale Service Directories]]></title>
<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=370</link>
<description><![CDATA[In this paper we describe the implementation of multiversion concurrency control on the Generalized Search Tree (GiST), an index structure introduced by Hellerstein. For large-scale service directories, the need arises for a data storage system capable of handling substantial amounts of multidimensional data efficiently, as well as being able to support queries which are natural to the type of data stored in the directory. The GiST is an indexing structure that lends itself particularly well to this type of application. However, the solutions that have been proposed to address concurrency control on the GiST do not meet the requirements of large-scale service directories. The solution proposed here optimizes towards highly concurrent read accesses that are far more frequent than updates to the stored data.1 .<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.18">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=371</link>
<description><![CDATA[As Web services increasingly become important in distributed computing, some of the flaws and limitations of this technology become more and more obvious. One of this flaws is the discovery of Web services through common methods. Research has been pursued in the field of "Semantic Web services". This research is driven by the idea, to describe the functionality of Web services as accurately as possible and to create programs automatically out of already existing Web services. In this paper we discuss a new method for discovery and analysis of Web services. Our approach uses a Vector Space Search Engine to index descriptions of already composed services. Rather than generating or automatically composing applications, this approach provides developers with a valuable utility to browse repositories based on already existing information. Furthermore, we propose some additional modifications to extract the maximum amount of semantics from existing service definition repositories. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.5">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=372</link>
<description><![CDATA[Current web services approaches have many limitations, especially with description, discovery and integration mechanisms. In this paper we present a novel software architecture called aspect-oriented web services (AOWS) which addresses these problems. AOWS uses descriptions of cross-cutting concerns between web services to give more complete descriptions of services, supporting richer dynamic discovery and seamless integration. We describe our architecture, a formal specification of it and an implementation using .NET web services technology. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.7">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=373</link>
<description><![CDATA[Application frameworks are widely used in software engineering to support reuse by capturing the shared architecture among a family of applications. Their role in Web service construction has, however, been mostly ignored. Reuse in general has rather been considered in the context of Web service composition than as a means to use existing implementations to build new services with related functionality. In this paper we discuss reuse in Web service development, focusing on families of Web services that share a common architecture and a set of functionalities. Techniques supporting reuse rely on identifying and managing variation points. We propose a categorization of possible variation points in service endpoints, WSDL descriptions, and business logic. A pattern-based approach for managing variation and specifying a Web service framework to an actual service application is introduced. The approach is applied to specify a sample Web service framework.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.19">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=374</link>
<description><![CDATA[Service-centric systems exist in a very dynamic environment, which requires these systems to adapt at runtime in order to keep fulfilling its QoS requirements to its users. In order to create self-adaptive service centric systems, developers not only design the service architecture, but need to design the self-adaptability aspects in a structured way. Current service standards and technologies do not provide a general architecture in which all aspects for self-adaptability can be designed. In this paper we propose DySOA (Dynamic Service-Oriented Architecture), an architecture that extends service-centric applications to make them selfadaptive. DySOA allows developers to explicitly model the process and components that deal with determining the QoS of the running system, with evaluating the QoS, and with reconfiguring the system when necessary. Having the DySOA elements explicit enables separation of concerns, making the DySOA elements adaptable at runtime and reusable in next versions. We demonstrate how to use DySOA with an example. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.10">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=375</link>
<description><![CDATA[We have designed and implemented a framework assisting client-side applications to utilize asynchronous Web services that deliver results by calling back the applications in the context of enterprise security. This framework can support a number of rich features such as the Single- Request/Multiple-Response (SRMR) message exchange pattern, resumable clients, intra-enterprise user and terminal mobility, and flexible interaction modes for client applications to communicate with asynchronous Web services. Practical deployment of this framework in a number of cases has illustrated that this framework can effectively minimize development efforts in facilitating client applications to use Web services with callbacks. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.1">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=376</link>
<description><![CDATA[In order for e-Government to be successful there is a strong requirement for approaches that are based on widely accepted technical standards and formal design methods. In this paper, we describe the architecture of the eMayor platform, a Web Services based platform that is built as a holistic service framework for the deployment and delivery of e-government enterprise services for European municipalities. The design of the platform is based on the ISO/RM-ODP standard. The goal of the paper is to present both a general architectural overview of the platform and its services, along with the engineering and technology aspects of the architecture as instances of the engineering and technology viewpoints of the RM-ODP standard. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.11">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=377</link>
<description><![CDATA[Convergence of information and telecommunication networks leading to integration of voice, data and video services will bring new opportunities for users as well as service providers. With a growing number of services available on the market, dynamic discovery of services, their composition, selection, mediation as well as execution will be required. In this paper we show how voice and data services can be seamlessly integrated using existing client as well as server VoIP systems based on a widely used SIP signaling protocol and newly emerging technologies in Semantic Web Services. Within particular use case scenario, we describe all phases of the call set-up between two call participants. We show how Semantic Web Services technology can facilitate dynamic and optimal integration of voice and data services with different characteristics while at the same time conforming to users’ needs and preferences.  <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.22">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=378</link>
<description><![CDATA[The successful progress of the Web Services concept demands flexible ways for Web Services to cooperate and to jointly fulfill a task that is requested by a client. In some applications, the execution of the task is not completely specified beforehand, but could rather be referred to as "best effort". One example is information searches. A flexible invocation of cooperating Web Services might mean that their identities are not known beforehand. To achieve trust in the outcome of the task, it is essential that the identities of the cooperating Web Services can be tracked in a secure way. It is also essential that the requesting client can decide to what degree the task has been executed. In this paper an approach to securely track identities of Web Services is introduced. The use of one-way messages creates a system where the state of a request is preserved by the request itself. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.21">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=379</link>
<description><![CDATA[WS-Coordination and WS-CF provide support for distributed activities that require coordination in an environment of Web Services. Both specifications are generic coordination frameworks, not specific for any application. Despite their generic character, up to now only transactional protocols have been defined, which leverage these coordination frameworks. In this work we map a distributed activity, that it is not related to transactions, onto the coordination model underlying WS-Coordination and WS-CF. Consequently we identify the necessary characteristics of a distributed activity that leverages the coordination frameworks of WS-Coordination and WS-CF. We also examine limits of these coordination frameworks and suggest additional mechanisms where support for coordination in particular use cases is not sufficient. In contrast to coordinating distributed transactions, additional problems could arise when other types of activities are subject to coordination. These problems are studied, classified and reviewed in conjunction with the architectural differences of WS-Coordination and WSCF. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.20">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=380</link>
<description><![CDATA[Tracking the execution of composite Web services to identify and adjust their specification according to the current features of the environment is a challenging issue. The concept of views, as a dynamic snapshot over this specification according to a given context, is proposed in this paper. A view is used as a support means for tracking the execution progress of composite Web services and deploying the corrective measures in case of non-compliance with users’ requirements. Our contributions are a definition of what a view means in the context of Web services composition, an approach for specifying user context and its respective view, and mechanisms for extracting and visualizing views over specifications of composite services. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.6">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=381</link>
<description><![CDATA[Fault management in Web Services composed by individual services from multiple suppliers currently relies on a local analysis, that does not span across individual services, thus limiting the effectiveness of recovery strategies. We propose to address this limitation of current standards for Web Service composition by employing Model-Based Diagnosis to enhance fault analysis. We propose to add Diagnostic Web Services to the set of Web Services providing the overall service, acting as supervisors of their execution, by identifying anomalies and explaining them in terms of faults to be repaired. This approach poses the basis for the development of specialized recovery and compensation techniques aimed at addressing different problems, which could not be otherwise discriminated. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.12">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=382</link>
<description><![CDATA[The goal of Web service effort is to achieve universal interoperability between applications by using Web standards: this emergent technology is a promising way to integrate business applications. A business process can then be seen as a set of Web services that could belong to different companies and interact with each other by sending messages. In that context, neither a global model nor a global mechanism are available to monitor and trace faults when the business process fails. In this paper, we address this issue and propose to use model-based reasoning approaches on Discrete-Event Systems (DES). This paper presents an automatic method to model Web service behaviors and their interactions as a set of synchronized discrete-event systems. This modeling is the first step before tracing the evolution of the business process and diagnosing business process faults. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.17">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Correctly described Web service will facilitate automatically discovery of web service in semantic web. In this paper, we present a content model for a better ontological metadata representation to facilitate Web service description. The proposed content model has two parts: content profile and process model. The content profile consists of three metadata, a core metadata, a structural metadata, and a semantic metadata, by which we can use to describe a Web service's basic properties, content structure and semantic meaning, respectively. The process model provide control construct to design complex service. We also provide a mechanism to transform a content model to a DAML-S Web service. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.3">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=384</link>
<description><![CDATA[For web-services to become pructdcal, an infrustructure needs to be supported that allows users and applications to discover, deploy, compose, and synthesize services automatically. This automation can take place only if a formal description of the web-services is available. In this paper we present an infrastructure using USDL (Universal Service-Semantics Description Language), a language for formally describing the semantics of web-services. USDL is based on the Web Ontology Language (OWL) and employs WordNet as a common basis for understanding the meaning of services. USDL can be regarded as formal service documentation that will allow sophisticated conceptual modeling and searching of available web-services, automated service composition, and other forms of automated service integration. A theory of safe service substitution for USDL is presented and proved sound and complete. The rationale behind the design of USDL along with its formal specification in OWL is presented with examples. We also compare USDL with other approaches like 0WL-S and WSML and show that USDL is complementary to these approaches. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.4">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=385</link>
<description><![CDATA[Internet, to locate target services in an accurate and efficient way becomes increasingly difficult. At present, semantic web service is regarded as the most promising approach to address the challenge. In this paper, an ontology service description language and a query language, OSDL and OSQL are proposed respectively, and then a service matchmaking algorithm based on interface semantics is proposed. The problem of service matchmaking can be attributed to the similarity between the semantic pair, and the similarity is the quantization of their relationship, which is discovered through reasoning on ontology. Unlike the existing semantics-based service matchmaking algorithms, which focus on the relationships among the successors and ancestors of ontology classes, the proposed one also pays attention to the comparability among classes and their property classes. The experiment data indicate that it is worthwhile to take the point into consideration to receive a higher recall and precision.<a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.14">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[A core paradigm of the Web is information exchange via persistent publication, i.e., one party publishes a piece of information on the Web, and any other party who knows the location of the resource can retrieve and process the information at any later point in time and without the need for synchronization with the original publisher. This functionality significantly contributed to the scalability of the Web, since it reduced the amount of interaction between the sender and the recipient. Current approaches of extending the World Wide Web from a collection of human-readable information, connecting humans, into a network that connects computing devices based on machine-processable semantics of data lack this feature and are instead based on tightly-coupled message exchange. In this paper, we (1) show that Web services based on the message-exchange paradigm are not fully compliant with core paradigms of the Web itself, (2) outline how the idea of persistent publication as a communication paradigm can be beneficially applied to Web services, and (3) propose a minimal architecture for fully Web-enabled Semantic Web services based on publication in shared information spaces, which we call Triple Space Computing. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.30">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Enterprise Digital Dashboard (EDD) is an effective tool for executives to get a top level view of their enterprise as well as closely linked partners. Decision makers need to have easy access to data such as total sales per month, inventory status and a number of other key performance indicators (KPI). These business needs are not in sync with the technological challenges such as the presence of disparate enterprise systems (e.g. ERP, SCM, CRM etc.). Web services is an effective technology to link disparate systems. This paper discusses a solution based on Web services in the context of EDD.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=979</link>
<description><![CDATA[With the increasing popularity of web services, a number of technologies have emerged that target the integration and composition of web services as lightweight components. However, a number of problems have been identified in these approaches, for example regarding an overly static integration and lacking support for the modularization of crosscutting concerns. In this paper, we evaluate FuseJ, an architectural description language for unifying aspects and components, as an approach for the composition of web services. We outline how FuseJ can be used to this end and present an evaluation that compares FuseJ to four other web service composition approaches according to criteria such as the organization and flexibility of the composition and the support for Aspect-Oriented Software Development (AOSD). Although FuseJ does not allow describing complete business processes, we find that it excels at selective and dynamic composition and that it supports advanced separation of concerns without the need to introduce additional constructs. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.13">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[The most promising feature of the Web services platform is its ability to form new services by combining the capabilities of existing services, i.e., its composability. The existing services may themselves be composed of other services, leading to a hierarchical composition. In a hierarchical composition, providers vary in the visibility they have over the other providers in the composition. For example, a provider may not be aware of any providers in the hierarchy other than its parent and children. On the other hand, a provider may be aware of all other providers in the hierarchy. Towards this end, we introduce the notion of Spheres of Visibility (SoV) as an abstraction to capture the upward/downward visibility aspects of the providers in a hierarchical composition. The latter part of this paper deals with compensation. We outline a compensation mechanism for hierarchical compositions conforming to the visibility restrictions modeled as SoV. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.23">buy now!</a><div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=978</link>
<description><![CDATA[Businesses are changing rapidly and organizations tend to act worldwide and are increasingly becoming distributed over the continents. As a consequence, distributed software systems have to keep track with rapidly changing markets. Business rules provide support for capturing some knowledge that changes frequently. Current business rule systems manage and execute business rules, however, typically lack support for increasingly distributed software systems, in particular, with respect to flexibility and reuse of business rules across distributed rule engines. In this paper we propose a service-oriented distributed business rules system that manages and deploys business rules to various business rule engines. Furthermore, we present the design and some implementation aspects of a service-oriented business rules system based on WS-Coordination. The system supports management and deployment of business rules to various business rules engines. Furthermore, we present a framework that unifies the access to several heterogeneous business rules engines, and we propose a solution that automatically generates and provisions Web services for executing business rules managed by a business rule engine. <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.28">buy now!</a><div></div><div></div>]]></description>

<description><![CDATA[Provision of services within a virtual framework for resource sharing across institutional boundaries has become an active research area. Many such services encode access to computational and data resources, comprising single machines to computational clusters. Such services can also be informational, and integrate different resources within an institution. Consequently, we envision a service rich environment in the future, where service consumers are represented by intelligent agents. If interaction between agents is automated, it is necessary for these agents to be able to automatically discover services and choose between a set of equivalent (or similar) services. In such a scenario trust serves as a benchmark to differentiate between services. In this paper we introduce a novel framework for automated service discovery and selection of Web Services based on a user’s trust policy. The framework is validated by a case study of data mining Web Services and is evaluated by an empirical experiment.  <a href="http://csdl2.computer.org/persagen/DLAbsToc.jsp?resourcePath=/dl/proceedings/ecows/&amp;toc=comp/proceedings/ecows/2005/2484/00/2484toc.xml&amp;DOI=10.1109/ECOWS.2005.2">buy now!</a><div></div><div></div>]]></description>
