摘　　要：Web服务是继SOA后的又一研究热点,存在于Internet上大量的Web服务必然会形成一个结构复杂、节点繁多,具有相互影响的复杂网络.目前国内外并没有提出完善的关于Web服务的复杂网络模型,对Web服务复杂网络特性的研究也处于发展阶段.提出以Web服务为节点,服务功能相似关系为边,构建复杂网络的模型和算法,并对构建的网络的特性展开研究.本文设计并实现了一个原型系统,利用Web服务的匹配关系构建了网络模型,并且证明该网络具有小世界特性和无标度特性.该方法的提出把对Web服务的研究从传统的SOA模型中引领到复杂网络模型中,对推动Web服务组合和发现等应用具有一定的指导意义.Web service becomes another hot topic following SOA, the massive Web services definitely will be organized as a complex network with the complex structures, numerous nodes and muttial influence. In research area, there is few work in both the proposing models and studying characteristics for complex network of Web service. In this paper, the approach of building complex network of web service is proposed, which treating the Web services as nodes of the complex network and the functional similarity of Web serv- ices as the edges of the complex network, the characteristics of network are also well studied. Based on the massive Web services, a prototype system is implemented which using the matches of service information for building network model, and further proving the the small world and scale-free properties of network. The proposed approach is helpful to shifting the research of Web services from the traditional SOA model to a complex network model, it is also has a certain instruction in promoting the application of Web service composition and discovery.
