摘要
在分析单一服务的发现方法和多个服务的动态组合方法基础上,提出一种面向组合服务的语义Web服务发现方法,能对语义Web服务进行形式化描述,实现了面向组合服务的语义Web服务注册结构及相应的数据维护算法;并设计一种面向组合服务的Web服务发现算法,该算法可以实现对单个服务的语义检索及对已有组合服务进行快速搜索,从而查找出满足要求的组合服务或组合服务片断,实现对已有组合服务的重用和快速检索.
After the Web service matching method which aims only at the single Web service and the dynamic composition method which aims at multiple Web services have been analyzed, a formal description of semantic Web service is proposed, based upon which a semantic Web service registry structure oriented for the composed Web service and the corresponding data maintenance algorithm have been implemented. In the meantime, a Web service model and discovery algorithm oriented for the composed Web service are proposed, which can be used to semantically match single Web service, and also to search in those composed Web services to find a composite Web service or composition Web service fragment which satisfy the search requests so that the composed Web service can be reused and the efficiency of the discovery can be improved.
