随着Web服务的快速发展,Web服务的数量急剧增加.分布式环境中如何快速准确的实现服务查询、组合成为当前亟需解决的问题.本文提出了一种基于结构化P2P网络的Web服务组合架构.它利用语义实现服务的精确匹配,同时使用扩展的OWL-S属性满足了用户个性化定制的需求,并且通过服务映像关联关系实现基于服务功能的快速分布式服务组合计算.本文的Web服务组合架构及分布式服务组合算法解决了分布式环境下服务查询和组合的所存在的一系列问题,提供了匹配用户个性化需求的服务组合结果,同时还提高了服务组合算法的执行效率.

With the rapid development of Web service,the number of Web services is increasing sharply. It has become an urgent problem to achieve the service discovery and composition in a rapid and accurate way in the distributed environment. This paper proposes a Web services composition architecture basing on the structured P2P network,which uses semantic to achieve service composition by service accurate matching. In addition, the user personality is satisfied by using the extended OWL-S attributes,and through WVM association to implement the fast computing of distributed service composition based on the service function. The Web service composition architecture and distributed service composition algorithm proposed in this paper solves a series of existent problems in service discovery and composition in distributed environment, and provides a service composition result meeting user personality requirement. At the same time, it improves the efficiency of service composition calculation.
