基于领域本体和QoS的服务选取方法

摘要

The work focuses not only on how to find right Web services that meet user' s requirements, but also to select the optimal solution and service in numerous similar services and composition schemes. It put forward an approach of selecting service which based on domain ontology and QoS attributes. It could formalize Web services into input and output semantics parameter based on the concept of domain ontology so as to conclude a series of Web services, which met functional requirement. It made full use of QoS attributes as well as decision evaluation to attain the optimal solution. In the end, the effectiveness and feasibility can be verified by means of the experiment.%针对如何在众多Web服务中找到满足功能需求的服务,又如何在多个相似服务和多个组合方案中寻求最优目标,提出一种基于领域本体概念和决策理论的服务选取方法.该方法首先借助领域本体概念,根据输入输出参数的语义找到满足功能需求的服务,在多个相似服务和多组合方案选择上,通过对各QoS属性综合决策评估出最优解.最后通过实验验证了该方法的有效性和可行性.
