摘要
针对基于关键词Web服务发现的不足,采用OWL-S作为服务描述语言,为Web服务添加语义描述,构建一种基于语义的Web服务发现机制。本文首先将Web服务请求进行语义解析,生成请求服务文档,然后在服务注册库中通过服务匹配算法,得到候选服务集,并借助线形评价标准对所选服务进行语义评估,为服务请求者选择最优的服务。
Aiming at the problem of Web services finding based on keywords, the paper uses Web ontology language for services as describing language of Web service to add semantic content for Web service to conceive a Web service discovery mechanism based on semantic. The paper processes semantic parse for Web service request, and creates Web service request document, then carries out service matching in service register warehouse for finding satisfy services, at the same time, applyies linear appraising criterion in the service set to choose optimization service for service demander.
