一种基于语义的Web服务发现策略

Web Service Binding Based on Semantic

随着计算机网络应用的不断发展,基于Xml的Web服务技术不断成熟。服务数量和种类不断增多,并逐步向大规模、海量化发展。如何在海量Web服务中高效、精确的选取目标服务成为研究课题。为了解决上述问题,本文提出了一种基于语义的WEB服务发现策略。通过定义系统本体,构建了服务词汇本体树。给出了基于本体树的服务标注方法,详细描述了海量服务数据处理策略。对基于用户驱动的服务绑定、用户需求信息的本体标注方法做了详细阐述。最后,通过实验证明了所提方法在提高服务的绑定效率和精度上具有优越性、可行性和正确性。

With the development of network technology, the Web service based on Xml has developed rapidly. More and more Web services have emerged. The researches on Web service binding oriented to massive services are getting more important. The strategy for web service binding based on semantic is proposed in this paper. The system ontology and the ontology tree are defined. The methods for marking Web services and data processing based on semantic are given. The strategy for service binding based on user requirement is discribed detailed. At last, the validity and superiority of proposed methods are illustrated by simulation experiment and comparative analysis.
