An Approach for Service Discovery Based on Semantic Peer-to-Peer

The service discovery is a key step during Peer-to-Peer (P2P) converging with Web Service. In this paper, a semantic-P2P 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’s node selection. Meanwhile, similarity functions are accentuated for measuring the semantic similarity of different elements inside a service profile. 1 Semantic-P2P based Service Discovery Framework At present, there are totally three kinds of pattern for Web Service discovery, as Matchmaking, Broker and P2P model. We introduce an expertise-based model for service discovery under P2P. In our model, every peer performs service provider and service consumer simultaneously. Each peer also has Local Service Registry (LSR) and knowledge repository (shown as Fig.1). The peers share an ontology O, which provides a common conceptualiz...
