摘　　要：Web服务已经成为互联网中最为重要的一种计算资源和软件资产,Web服务的大量涌现对服务发现提出了挑战。Web服务发现的关键是Web服务的语义描述的准确性和Web服务检索引擎的检索效率。提出了一种基于本体的Web服务描述方法,采用OWL-S对Web服务进行语义描述,并提出了针对性的Web服务检索引擎。通过试验,该模型结合语义Web服务技术实现Web服务的动态查找与组合,可提高Web服务发现的查全率和查准率。Web services have already become one of the most important computing resources and software assets in the Internet. With the increasing number of Web services,how to find the required services efficiently or how to gain the best service from the vast service sets become important. The semantic description of Web service and the efficiency of OWL-S retrieval model of semantic Web service are the key to the discovery of the Web service. This article proposes the OWL-S framework of semantic Web service,and adopts OWL-S to describe the Web service,and raises pointed matching algorithm. Through experiments,in this model,together with the semantic Web service technology,the dynamical searching and composition of Web service are implemented,so that the precision ratio and the recall ratio of Web service can be improved.
