Abstract: It is urgent to find effective methods of service discovery with the emergence of large number of Web services.Semantic Web services combine semantic Web with Web services and make full use of semantic to enhance Web services.The same ontology is used to describe the knowledge of services selector and provider in the most of existing semantic Web service discovery researches.Services selector and provider use different ontologies in the real world.Aiming at the problem of semantic web services discovery,a new algorithm is put forward to calculate similarity of different ontology concepts and a method of semantic web services discovery based on multi-ontologies is proposed.Test results show that the method in the paper is effective.

Key words: multi-ontology, semantic Web services, discovery

摘要: 随着大量Web服务的出现,迫切需要高效的服务发现方法。语义Web服务将Web服务和语义相结合,充分利用语义增强Web服务。现有的语义Web服务发现研究中,大多采用同一本体描述服务需求方和提供方的知识。而现实世界里,很多时候服务需求方和服务提供方采用了不同的本体。针对多本体下的语义Web服务发现问题,给出了一种新的计算不同本体概念相似性的算法,提出了基于多本体的语义Web服务发现方法。实验结果表明了该方法的有效性。
