摘　　要：传统的Web服务发现只是简单的基于关键字的语法匹配,查询得到的服务往往不是用户想要的,如何正确定位合适的Web服务成为主要问题。在服务使用OWL-S描述的前提下,服务匹配通常认为是本体概念的匹配,给出了一种基于语义Web服务的匹配算法,通过服务发布者提供的服务和服务消费者寻求的服务的关系来进行匹配算法研究,提出了相应的服务匹配技术,详细介绍了服务请求时进行服务匹配使用的匹配算法,达到服务发布者和请求者可以实现语义的匹配。最后对服务匹配算法进行了实现,提高了服务的查准率和查全率。Traditional Web service discovery is just a kind of simple syntax match based on keywords.The services resulted from such queries are often not what the users expected.How to locate the right services is becoming a big challenge.Under the precondition of service described by OWL-S,service matching is generally considered as the matching of ontology concepts.A matching algorithm is presented based on semantic Web service,and the relationship of services provided by the publisher and consumer is studied to carry out matching algorithm,then the corresponding service matching techniques are put forward,the service matching arithmetic is introduced detailedly,which can realize the semantic matching between service delivery and the requester.At the end,the service matching algorithm is achieved,it can improve service precision and recall ratio.
