摘　　要：分析集中式语义Web服务发现机制存在的问题,利用P2P和本体技术,提出一种基于P2P的语义Web服务发现机制。将服务的部署与发布无缝地绑定在一起,按应用领域和服务目标将整个P2P网络组织成3层结构,基于该结构建立3阶段服务发现算法,达到优化网络结构、提高服务发现效率的目的。This paper analyzes problems of centralized semantic Web service discovery mechanism, utilizes P2P and ontology technology, and presents a semantic Web service discovery mechanism based on P2E The deployment and publication of a Web service are bound together. P2P networks are organized into three-layer structure according to application domain and service goal, and three-step service discovery algorithm is established based on this structure to optimize network structure and improve service discovery efficiency.
