摘要 随着Web服务数目的增长和对实时性需求的增加,单一集中式的UDDI服务注册中心难以满足实际需求,而基于某个领域的UDDI虽然查找迅速却难以满足所有用户的要求,于是如何组织一个逻辑上完整的服务注册中为Web服务应用的一个新研究方向。基于P2P的底部架构,将服务注册中心作为P2P网络内基本节点,提出了一个根据本体信息对服务注册节点进行语义分类查找的Web服务发现模型。在模型的基础上,提出了在P2P层支持语义的一种发现的方法。提出的Web服务发现模型既结合了集中式Web服务发现方式和分布式Web服务方式发现的优点,又创新性地在P2P发现方面加入了本体信息。 Service discovery plays a very important role in web service applications. As the growth of web services numbers, a single UDDI can not meet users' need. Although specific domain based UDDI can search rapidly, it can not satisfy all users need as its domain restrict. So how to build a web services discovery system with logical integrity becomes an important research issue. A web services discovery architecture based on P2P environment is introduced. Regis^es of different domain are seen as basic P2P nodes and organized in the P2P environment. Also, there lies a new novel method in semantic discovery based on P2P environment. The proposed model have the advantages of centralized web services method and decentralized web services discovery method. Also, a novel semantic discovery method is used in P2P based on ontology.
