Semantic-Overlay-Driven Web Services Discovery

There are many common characteristics between Web service (WS) and peer-to-peer (P2P) computing environment. Therefore, carrying out Web service over P2P network can utilize the advantages of P2P to achieve the services integration and resource self-government. The service discovery is a key step during this convergence. In this paper, a semantic-overlay based approach is presented for Web service discovery. To enable the semantic web service superiority, service profile is used to describe Web service and as the service data source. The service-expertise based model is proposed for service node selection. Meanwhile, similarity functions are discussed for measuring the semantic similarity of different elements inside a service profile.
