Word Net-Enhanced Dynamic Semantic Web Services Discovery

Web services are software systems designed to support interoperable machine-to-machine interaction over a network. There are mainly two problems in Web services discovery: how to describe service accurately and delicately to support precisely matchmaking and how to store, index and exchange the information of Web services in order to extend the scope of service discovery and guarantee the acceptable processing time of service discovery. In this paper we proposed a method for semantic Web services discovery using structured P2P technology. The service is published by the output concepts of service model in OWL-S. The service discovery is a two-steps task, service location through output concepts and service matchmaking through input concepts. Furthermore, we proposed the hashing technology based on synsets of WordNet to overcome the problem of lack of semantic information and only supporting exact searching in structured P2P networks.
