Service discovery is vital for the expansion of Web services and is often identified as one of the most challenging problems for the wide-scale use of Web services. As the number of Web services is increasing on the web, service discovery is becoming a major issue. To address this issue, UDDI registry has been developed by standard bodies. However, the challenge is no longer in providing information anytime, anywhere but in providing precise and accurate information to the users in real time. UDDI lacks in these characteristics because searching mechanism of UDDI is based on keyword matching. Service discovery is limited to service name and classification. Current registry-based approach for service discovery is a passive style registry, which essentially provides service information in response to a request. There is no way to push information towards service users.In this paper, we propose a proactive registry for efficient discovery that utilizes semantic-based publish-subscribe model. We use proactive push approach for providing service notifications to service requester and semantic based capability matching of OWL-S Web service descriptions. The algorithm assigns scores to individual concepts of the advertised service by concept matching with that of the requested one and then assigns overall ranking to advertisement on the basis of individual scores. The results show a significant increase in precision and recall of service discovery as compared to UDDI approach and other semantic based approaches.

“…Aiming at the situation that Web service based WSDL is lacking of semantic information impedes the dynamic and adaptive interaction among services, the research focus of Semantic Web Services (SWS) [27,28] under the background of Semantic Web is to depict services using Ontology technique (OWL-S, WSMO (Web Service Modeling Ontology), WSMO-Lite, SAWSDL METEOR-S etc. ), or to expand semantics of current solutions, thus web services can be understood consistently by different machines, thus promote automated service discovering [29][30][31][32], composition and interaction [33,34].…”

Web service composition has received much interest due to its potential to achieve the visionary promise of Service-Oriented Computing paradigm in which services can be utilized as the basic constructs to create flexible dynamic business processes and agile applications that may span organizations and computing platforms with little effort even automatically. In this paper, we proposed a snowball method for automated Web service composition which is based on service relation tracing which starts off rather like a standard ego-centered network study. It discoveries one or several available Web services which can accept the input parameters in user requirement through sematic reasoning and determines whether its output parameters meet the user requirements. And then it fetches other candidate services following the Sequential-total and Sequential-partial relations, investigates their outputs, also asks further sequential relations, and so forth through a succession of "waves" of spreading. So the process is repeated and the composite service is constructed incrementally tracing sequential relations in Service Network just like a snowball. The experiment shows that the approach proposed in this paper can greatly improve the accuracy and efficiency of Web service composition.
