摘　　要：Web服务是一种比较成熟的分布式计算技术，拥有自己特有的协议和运行模型，而p2p同样拥有一组成熟的协议和技术，该文简单介绍了p2p的Napster和Chord两种技术，并将其和Web服务技术结合讨论，类比两个领域的技术畀同，借鉴Chord技术的优点，引入了语义信息对Web服务进行本体描述，建立了一个新的模型。设计了一种通过比较语义相似度来选择和组合分布在Chord环上的Web服务的算法模型，并对该模型的优缺点进行评价，讨论了一些改进的方法和未来的可能性。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.
