【摘要】 如何准确而又高效地匹配零散分布于各地的W eb服务,通过分析现有的一些相关研究,在P2P网络的基础上提出了支持QoS的语义W eb服务匹配模型。模型首先分析了P2P网络的特点,在扩展UDD I的基础上,结合目前语义W eb服务匹配的多层匹配思想,提出一个三层次的匹配筛选算法,并对基本描述、语义W eb服务匹配、服务质量各层的匹配算法进行了深入讨论,用相似函数来度量服务提供方与服务请求方的W eb服务相似程度,为W eb服务匹配和发现提供了一种有效的方法。更多还原

【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.更多还原
