摘　　要：目前,Web服务的发现一般是通过集中式的UDDI注册中心实现,通常会导致一些缺点。因此提出一种分布式UDDI网络和基于层次聚类的语义Web服务发现算法。性能分析表明,在保证查全率和查准率的同时,减少了节点访问量和查询时间。Presently, Web services are generally discovered on a centralized registry, which may lead to many drawbacks. Therefore, a distributed UDDI registry network and DHCS-based discovery mechanism of semantic Web services in P2P environment is presented and discussed. Finally, some metrics are introduced to evaluate the discovery performance on the bases of protecting correct-rate and complete-rate of the examinations.

关 键 词：语义WEB服务 分布式UDDI 发现机制
