摘　　要：在P2P网络中,有大量的Web服务,如何准确高效的发现零散分布于世界各地的语义Web服务呢?文章从P2P网络的特点出发,分析了现有的一些研究和方法,在扩展UDDI的基础上,结合目前语义Web服务匹配的多层匹配思想,提出了P2P网络中支持QoS的语义Web服务匹配和发现的有效方法。该方法采用一个四层次的匹配筛选算法,对QoS各层的匹配算法进行了深入讨论,并以相似函数来度量服务提供方与服务请求方的Web服务相似程度。In the P2P network, there are a large number of Web services. How to find the Web service that distribute different locations efficiently and exactly？ In this paper, we first analysis the existing research and methods based on the extended UDDI from the characteristics of P2P networks. And combine to the current multi-match ideas of semantic Web services. A P2P network to support QoS of semantic Web service matching and found an effective way was put forward. The method used to match a four-level filter algorithm, QoS at all levels of the matching algorithm were discussed in depth and a similar function to measure the service request and service provider side is similar to the level of Web services.
