A Grid service is an extended Web service that conforms to the Open Grid Service Infrastructure (OGSI) specification. The capability that existing Web service technology express is relatively weak. The publishing and discovery of Grid resource are crucial steps in Grid computing. In this paper, we propose a novel semantics based Grid Service framework which support publishing and discovery of G...

We provide a conceptual model for context aware Semantic Web Service (SWS) discovery, which can utilize realtime legacy data from external systems and support user contextbased service discovery and selection. This model offers advantages over current SWS technology which cannot be easily applied to different domains or be integrated with legacy systems. Using this conceptualization we propose ...

This article proposes a system architecture of a case based web services reasoner, CWSR, looks at the correspondence relationship between the main activities of CBR and those of web services, and proposes a unified approach for case-based web service discovery, composition and recommendation. The proposed approach will facilitate the research and development of web services, e-services, intelli...

Web services have acquired enormous popularity among software developers. This popularity has motivated developers to publish a large number of Web service descriptions in UDDI registries. Although these registries provide search facilities, they are still rather difficult to use and often require service consumers to spend too much time manually browsing and selecting service descriptions. Thi...

Recently, the use and deployment of web services has dramatically increased. This is due to the easiness, interoperability, and flexibility that web services offer to the software systems, which other software structures don't support or support poorly. Web services discovery became more important and research conducted in this area became more critical. With the increasing number of published ...

While Web Services already provide distributed operation execution, the registration and discovery with UDDI is still based on a centralized repository. In this paper we propose a distributed XML repository, based on a Peer-to-Peer infrastructure called pXRepository for Web Service discovery. In pXRepository, the service descriptions are managed in a completely decentralized way. Moreover, sinc...
