摘要
随着各种已有Web服务数量的日趋增加,如何快速发现可用的Web服务变得愈加重要。而随着语义Web服务的不断发展,Web服务发现也从原来的单纯采用关键字或简单分类逐渐转变为更多地使用语义信息。发现的关键在于匹配,而目前一些较成熟的技术,如OWL-S,采用了本体技术对Web服务进行描述,因此,文章提出了一个基于图相似性的本体匹配算法,通过构建Web服务本体并转化成标记图进行匹配,实现语义Web服务描述的匹配,从而准确快速地发现满足特定需求的Web服务。
A number of web services are available and therefore it becomes more important to discovery these web services in a short time. As the development of semantic web service, it uses semantic information instead of key word or simple classification in web service discovery. Matching is the key of discovery, and some developed technologies such as OWL-S, use the ontology to describe the web service. Therefore, by building web service ontology and transporting it to label graph for matching, we design a graph-similarity-based ontology matching "algorithm, to match the semantic web service description, so as to find the required web service accurately and fast.
