摘　　要：为了提高语义Web服务组合系统的扩展性、可靠性和稳定性,提出了一种基于P2P的语义Web服务(P2PSWS)组合系统架构.该架构结合了集中式和分布式结构的优点,将统一描述、发现和集成协议的功能分散于本地Web节点、组Web节点和公共Web节点;设计了一种基于内容寻址网络的P2P网络语义Web服务的定位机制,以保证每个共享服务按领域划分,按被所有节点所共享的公共Web节点来注册.原型系统运行表明,该架构有助于克服传统公共Web服务结构上的单一节点失败问题,扩展了P2P系统的能力,有效地实现了基于本体的语义Web服务的组合.A P2P-based semantic Web services （P2PSWS） composition system architecture is presented to improve the scalability, reliability and stability of semantic Web service composition systems. The architecture combines the advantages of centralized structure and distributed structure, and distributes the function of UDDI to the local Web node, group Web nodes and public Web nodes. A location mechanism of semantic Web services is designed based on CAN （contentaddressable network） P2P networks to ensure that each service is registered in one node of the public Web. The registration services of public Web nodes are divided by areas and shared by all nodes. The running of prototype system shows that the proposed structure helps to overcome the problem ＂the failure of a single node＂ on the traditional structures of public Web services and expands the capacity of P2P systems, and achieves an efficient ontology-based semantic Web services composition.
