分析了语义Web服务中存在的本体异构问题,讨论了语义Web服务发现中输入、输出匹配的方法,以及本体映射中概念相似度计算方法。在已有的Web服务模型基础上,引入语义Web服务发现的机制,提出了一个基于本体映射的语义Web服务发现框架,并阐述了其实现机制。该框架下的本体映射技术的应用能够增强语义Web服务发现的能力。
The problem of ontology heterogeneity in semantic web service is analyzed,the methods of inputs/outputs matching in semantic web service discovery and the methods of similarity computing in ontology mapping are discussed.On the basis of the existing web service model,the mechanism of semantic web service discovery is introduced,then a framework of semantic web service discovery based on ontology mapping is proposed,and its realization mechanism is illustrated.The application of ontology mapping technology under this framework enhance the capability of web service discovery.
