International Journal of Web Services Research (JWSR), Volume 2, Number 3, July-September 2005.
This issue of the International Journal of Web Services Research (JWSR) collects five papers that span from Web Services discovery and development, state management for Web Services composition, information service for Grid computing, and Web service-based personalized Web mining. Special thanks to guest editors Dr. Savas Parastatidis and Dr. Jim Webber for their help in organizing quality papers.
Swapna Oundhakar, et al. address the problem of Web service registration and discovery in a registry federation, which is a collection of autonomous but cooperating Web service registries. They present an ontologybased Web service discovery infrastructure (METEOR-S Web Service Discovery Infrastructure). The discovery algorithm is based upon quantitative measures of the syntactic similarity and the functional similarity between a specified search template and a set of registered Web Services. The empirical evaludation uses a set of Web Services from the stock domain, and preliminary results are reported.
Bing Li and Wei-Tek Tsai propose an ontology-based service-oriented methodology to develop and integrate distributed applications. In their approach, requirements specification are elicited and analyzed based upon a service’s point of view, each service is then modeled and described using ontology. That is why the design process is called Ontology and Service Oriented (OSO) programming, and the output of the procedure is called OSO code. Since business logic in OSO code is represented in a machine-understandable format, the subsequent procedure of business process integration can be performed automatically.
Wei Jie, et al. present a hierarchical information service for a computational Grid virtual organization in order to ensure the provision of essential information for a computational Grid. Three layers are identified to support the information service; namely, a virtual organization layer, a site layer, and a resource layer. Based upon performance evaluation of a set of experiments over different models of information data organization, they introduce a novel data organization model. The implementation of their information service is based on the Globus Toolkit and complies with the OGSI (Open Grid Services Infrastructure) specifications.
Marty Humphrey and Glenn Wasson argue that Web Services Resource Framework (WSRF) and WS-Notification are core elements to manage states between Web
Services components in order to support effective construction of complex Grid applications. They present an empirical study paper discussing the architectural foundations of WSRF.NET, which is an implementation of the full set of specifications for WSRF and WS-Notification on the Microsoft .NET framework. Their study discusses the architectural implications of the WSRF on the designs and implementations of both WSRF implementations and applications. The observations
and lessons learned from the WSRF.NET project provide a basis for further evaluation of the WSRF approach.
Finally, Abdelsalam (Sumi) Helal and Jingting Lu propose a Web service-based information fusion framework that intends to enable end users to collect scattered information from diverse autonomous Web Services. Based upon personal data accumulated, a repeatable process is created transparently by which newer instances of the same information can be obtained in the future. A servlet server provides an intermediary broker layer to interact with services.
