基于多阶段匹配的语义Web服务发现框架

随着Web服务的高速发展和广泛应用,如何在众多的Web服务中找出用户所需要的Web服务成为了一个关键的问题.在语义Web服务研究的基础上,提出了一种新的多阶段匹配的语义Web服务发现框架,将整个发现过程分为服务类别、服务功能、服务名称和服务文本语句匹配4个阶段,并在服务功能匹配阶段针对本体库中概念间的密度问题,提出了基于信息量的改进GCSM算法,在服务名称和服务文本语句匹配阶段,针对中文多义词的问题提出了基于实例搭配和基本义原的消歧策略.最后,实验证明提出的发现框架具有较好的可行性和有效性.

Framework of Semantic Web Service Discovery Based on Multi-phase Matching

With the rapid development and extensive application of Web services,how to find a Web services that users need in many Web services becomes a key issue. Based on semantic Web service's research, we proposed a framework of semantic Web service discovery based on multi-phase matching. We divided the entire discovery process into service type,service function, service name and service text statements matching four stages. In service function matching stage, for the density between concepts on domain ontology library, we proposed the improved GCSM algorithm based on the amount of information. In the service name and text statements matching stage, for polysemy problem, we proposed a disambiguation strategy based on instances and basic meaning. Finally, the discovery framework was proved to be feasible and effective.
