摘要： 分析了XML Schema和DAML文档，发掘二者在组成结构上的相似性，提出了一种联系WSDL文件和DAML本体描述文件的中间数据模型，通过将XML Schema格式的WSDL文件和DAML描述的本体文件映射到这种公共的数据模型上，使二者可以进行比较匹配，从而为自动化的语义注释提供支持。实验结果证明，该方法能为Web服务描述文件自动地添加语义信息。

Abstract: This paper analyses the similarity between XML schema and DAML and develops a kind of common middle data model which can bridge both of them so that they can be matched by the way of mapping XML schema and DAML to the common data model. By doing so, this method can facilitate adding semantics to Web service automatically, which has been proved by experiments. The result shows that the method is worth being further studied and has a wide application foreground because it is necessary for adding semantics and efficiently to Web service precisely to store a mass of ontologies during the research work of Web service composition based on ontologies.

Key words: Web service, ontology, semantics, WSDL, DAML
