Abstract:
Services discovery based on syntactic matching cannot adapt to the open and dynamic environment of the web.To select the proper one from the web services candidate set provided by syntactic matching, a service selection method based on semantic similarity is proposed.First, this method defines a web services ontology including QoS and context as semantic supporting, which also provides a set of terms to describe the interfaces of web services.Secondly, the similarity degree of two web services is evaluated by computing the semantic distances of those terms used to describe interfaces.Compared with existing methods, interfaces of web services can be interpreted under ontology, because it provides a formal and semantic specification of conceptualization.Meanwhile, efficiency and accuracy of services selection are improved.
基于语法匹配的服务发现无法适应web的开放性和动态性环境.为了对语法匹配产生的web服务候选集进行二次选择, 提出一种基于语义相似性的web服务选择方法.该方法首先定义了包含QoS和上下文的web服务本体.服务本体提供了一个接口描述的通用术语集合, 以此作为服务描述的语义支撑.然后, 通过相似理论和web服务本体计算web服务接口之间的语义距离.与已有的方法相比, 由于提供了概念化的形式语义说明, web服务的接口能在本体下得到准确的解释, 同时服务选择的效率和准确性得到了改进.
