摘要: 针对如何高效而又准确地发现分布于各地Web服务的问题,基于P2P网络和语义描述提出一种新型服务发现机制,将服务按照语义动态地注册于由委托(broker)管理的不同节点簇,并将语义相似的节点簇组成虚拟语义网,提高了查询效率;采用反馈机制主动监测拓扑节点,和利用节点簇之间的分裂与聚合机制来保证该模型的有效性和性能.最后通过对原型系统的实现证明了该机制的合理性与有效性.

Abstract: To solve how to find the Web Service that distribute different locations efficiently and exactly, a new discovery schema for service based on P2P network and semantic description was put forward. The peers in model dynamically registered to different peer-clusters, which were managed by broker according to their services- semantic classes, and friend peer-clusters which had the similar semantic classes came into being a virtual network, and it improved the efficiency of querying. Moreover, the schema adopted feedback to monitor the peers in net actively and splitting-converging to guarantee the abilities for available. With implementing the prototype, the reasonability and validity of the schema were proved.
