A service broker based architecture for effective discovery and automatic publishing of Internet Web services

摘要

Web Services available “on the Web” provides unlimited values for the great number of online service consumers and Web application developers. With the widespread proliferation of Web services, finding the relevant services for clients and developers of service oriented application is a complex task. In this paper, we present the architecture with a service broker (registry) which facilitates an effective Web service discovery and automatic publishing. The proposed broker architecture crawls WWW to explore and publish the Web services with the broker. The broker facilitates Web service discovery mechanism which exploits the strengths of functional semantics, keyword matching, structural & syntactic matching and semantic. The broker architecture with automatic Web service publishing and discovery mechanisms is implemented and the experimentation reveals that, the discovery mechanism is effective in terms of Recall and Precision.
