Web Service has emerged as a dominant paradigm for distributed computing in industry as well as academia. Current Web service discovery methods are based on centralized approaches where Web services are identified based on service functionality. However, as the number of Web Services grows and becomes more dynamic, such a centralized approach quickly becomes impractical, which suffers from problems such as high operational and maintenance cost, single point of failure, and scalability. This paper proposes a semantic web based peer-to-peer architecture for building dynamic, scalable, decentralized service discovery and binding mechanism used for intelligent business process platform of Virtual Travel Agency. In addition, it integrates a scalable mechanism to rank Web services based on domain ontology and group ontology used for service publication, discovery and process generation. Finally, the performance analysis and evaluation of the method has been discussed and the prospects for the future research are presented.
