Web services is a comparatively mature distributed computing technology, it has its own protocols and operation model, while p2p also has a lot of mature protocols and technologies. This article simply introduces two p2p technologies: Napster and Chord, and combine them with the technologies of Web services. It also compares technologies of the two fields, given the advantages of Chord, the semantic information was used to describe the ontology of web services. In this article a new model was designed and an algorism model that how to choose and combine web services that distributed in the Chord circle, by comparing the semantic similarity, is devised. Some of the advantages and disadvantages of the model were discussed, finally the article talks about some improving methods and future possibilities for the model.
