基于相似度的语义Web服务发现技术研究

Research on Similarity-Based Semantic Web Services Discovery

针对传统Web服务在服务发现中存在效率低的问题,应用语义Web技术和本体理论,提出了一种基于相似度的语义Web服务发现模型。采用Web本体语言(OWL-S)描述Web服务,发布服务时包含充分的语义信息,在服务搜索中加入本体推理过程,综合度量服务的功能匹配程度和信誉值。实验结果表明,语义Web服务发现方法的查准率和查全率高于UDDI基于关键字的查找方法。

Aiming at the problems of low efficiency in service discovery of traditional web service,a similarity-based semantic web service discovery model is proposed,with the application of semantic web technology and ontology.The mechanism uses Ontology Web Language for Service（OWL_S） to describe web service and publishes service with semantic information.Ontology reasoning is added into service searching to measure its degree of functional matching and reputation value.The experiments suggest that the proposed method is better than that of Universal Description Discovery and Integration（UDDI） in precision and recall ratio.
