摘　　要：为了对W eb服务语义信息进行描述,提出了一种W eb服务语义标注方法。以现有的W eb服务描述语言(W SDL)文件为基础,充分利用W SDL中XM L schem a的语义信息与本体实体的相似性,从W SDL文件中抽取语义信息,并利用实体之间的名称相似度与结构相似度进行语义标注,生成基于OW L-S的W eb服务语义描述。用该方法对多个领域的W eb服务进行了语义标注,标注正确率在92.5%以上,较好地解决了W eb服务的语义标注问题。The current Web service description standard, Web service description language （WSDL）, lacks semantic descriptions even though semantic Web services can improve the discovery and composition accuracy of Web services. Web service semantic annotations add semantic information to the service description. An annotation method was developed to first extract semantic information from the WSDL file according to the similarities between the XML schema and the ontology entity. Then, the extracted information is annotated using the name similarities and structural similarities between ontology entities. Finally, a semantic description of the Web service.is generated in OWL-S format. Tests annotating dozens of Web services in various domains had an accurate rate of 92. 5%.
