| 摘 要： | 将语义Web技术引入Web服务研究,提出一种基于资源本体的Web服务发现和组合方法。通过分析资源之间关系,建立了基于上下位资源查找的Web服务发现方法;通过分析资源与服务的输入输出关系,建立了一种逐级查找的Web服务组合方法。与基于关键字和Web服务语义的Web服务发现和组合方法相比,基于资源本体的方法能较好地满足服务查全率和查准率的要求,具有较高的组合质量和效率,非常适合与资源密切相关的Web服务。

| Abstract: | In this paper we introduce the semantic Web technology to Web services research,propose a discovery and composition method for Web services which is based on resource ontology.By analysing the relationship between resources,a Web service discovery method based on searching father and son resource class is established.By analysing the input and output relationship between resource and services,a Web service composition methods of step-by-step searching is established as well.Compared with the Web discovery and composition method based on keyword and Web services semantics,the proposed method is fairly good in meeting the requirements of services recall and precision rates,has quite high quality and efficiency on service combination,and fits the Web services closely related to the resources a great deal. |
