Abstract
While Web services already provide distributed operation execution, service publication and discovery with UDDI (Universal Description, Discovery and Integration) is still based on a centralized design. In this paper, we present an approach for distributed Web services organization by combining the capabilities of Semantic Web services with the dynamics and real-time search capabilities of peer to peer (P2P) networks. Furthermore, we use domain ontology to provide enhanced semantic Web service annotation. A DHT (distributed hash table) based catalog service is used to store the semantic indexes for direct and flexible service publication and discovery. For partnership federation, we have made improvements for this architecture. We use category ontology to organize domain specific service enabling semantic classification of service based on domains. Thus service publication and discovery is within the federate partners. We have proposed the decentralized Web service organization architecture and discussed the procedure of service publication and discovery.
