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%.
