Abstract:To solve how to find the Web service that distribute different locations efficiently and exactly,analyzed existing related researches, and put forward a new matching model for service based on P2P network and semantic description. In this model, this paper first analyzed the P2P network. Combine the thought of multi-level matching approach based on extended UDDI, presented a kind of matching and filter algorithm with three level, each of algorithm , namely basic description, thoroughly discussed semantic Web service matching and QoS matching, introduced similarity functions to measure Web service similarity degree of provider and requester, this approach will be significant to Web services discovery. ......
