基于UDDI的语义Web服务门户的设计与实现

The Design and Implementation of Semantic Web Service Portal Based on UDDI

统一描述发现集成协议（UDDI）提供了Web服务的信息注册查找规范，解决了Web服务的描述、发布以及查找问题。然而采用UDDI建立的Web服务在服务查找时会受关键词匹配的严重影响，缺乏对语义信息的支持。因此在服务匹配时不能搜索到用不同术语描述的相关信息，从而造成了服务查全率查准率低。语义Web服务技术以信息服务智能化、自动化、高效性为目标，通过本体（Ontology）来描述资源的语义信息，它能够有效的解决上述问题。本文在分析了语义Web服务和UDDI技术规范的基础上。设计实现了一种基于UDDI的语义WEB服务的发布及发现机制。

Universal Description and Distributed Integration Protocol could provide the specification of information registration and solve the description, publication and finding of Web Service. However, the Web Service which was based on the UDDI would be influenced by the keyword and is lack of support for semantic information, so it could not find useful information, which is described by different terminology, and then cause the low precision. The Semantic Web Service have the ability of intelligent, automatic and efficiency, which could solve above problems through Ontology to describe the semantic information of resources. This paper designs and implements a mechanism of publishing and discovering Semantic Web Service, which is based on the specification of Semantic Web Service and UDDI.
