摘要 Web服务的大量涌现对服务发现提出了挑战,UDDI上基于关键词和简单分类的服务发现机制已经不能很好满足需要.该文在分析现有相关研究的基础上,提出了基于本体论和词汇语义相似度的 Web服务发现方法.通过构建Web服务本体,给出一个明晰的Web服务发现的研究对象,指出可对Web服务进行的几种相似度计算,并对其中的词汇语义相似度计算进行详细讨论.文中具体给出两种词汇语义相似度计算方法,其中第一种方法计算词汇语义相似度基于词语间距离度量,第二种方法计算词汇语义相似度则建立在义原相似度基础上.引入本体论和词汇语义相似度,为Web服务相似度计算、Web服务发现提供了一种有效可行的方法. Current infrastructure of Web services discovery such as UDDI provides text and taxonomy based search capabilities. With the large growth in number of Web services, the current Web service discovery mechanism becomes inefficient. Ontology and similarity based discovery or matching of services is a promising approach to address this challenge. This paper proposes Web service ontology and indicates several approaches to measuring similarity on this ontology. The method based on similarity of words which can be estimated in two ways is discussed in detail. This approach used in project will significantly improve Web services discovery.
