摘　　要：对于物联网服务的描述,现有的标准是基于XML(Extensible Markup Language)的WSDL(Web Services Description Language)语言,但WSDL语言不能对物联网服务进行语义方面的描述,从而影响了服务发现的准确率。在现有的语义服务描述语言中,OWL-S(Ontology Web Language for Services)语言的影响力最为深远。为了对物联网服务进行语义化描述,提出一种从WSDL到OWL-S的转换方法。通过操作映射和本体映射,该方法能够将已有WSDL文件转换为OWL-S文件。通过一些测试集合和实例验证了所提方法对文件转换的有效性,而且转换结果的查准率和查全率优于MWSAF方法。Aiming at the description of IoT services,the existing standard is WSDL(Web Services Description Language) based on the XML(Extensible Markup Language).However,WSDL lacks semantic information and can not describe the IoT services semantically,thus having an impact on the accuracy of service discovery.Among the current exi- sting semantic service description languages,OWL-S (Ontology Web Language for Services) has a most profound and lasting influence.In order to describe services semantically,this paper presented a conversion method from WSDL to OWL-S.This method can convert the existing WSDL file to OWL-S file through operation mapping and ontology mapping.Some test sets and examples verify the effectiveness of the proposed method for converting files.And the precision ratio and recall ratio of the conversion results are better than that of MWSAF method.
