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...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。展开更多

Semantic matchmaking plays a vital role in the automated and dynamic discovery process of Semantic Web Services and consists in measuring the semantic distance between a requested service and an advertised one. In this paper, an innovative approach to effectively compute the semantic distance between Ontology Web Language for Services （OWL-S） annotated services is proposed. First, an edge-based method for measuring the semantic distance between Web Ontology Language （OWL） concepts is presented. Then, a comparison of the proposed measure and the one presented in a recent related work is made in order to show that our method is more efficient and fine-grained. Finally, some equations to compute semantic matchmaking of service capabilities, which are expressed in terms of inputs and outputs, are presented.展开更多
