摘要 服务匹配是Web服务选择的重要前提。针对目前Web服务发现中过分依赖Web服务的功能性属性这一方法的不足,提出了一种基于非功能性Web服务质量QoS本体的Web服务选择Broker模型。之后,介绍了用来描述用户的个人偏好QoSPPR,量化了用户模糊需求;给出了QoS值计算函数公式。最后,依据Broker模型和QoS值计算公式提出了服务选择匹配算法。 Web services' matchmaking is an important precondition for Web service selection. As current Web service discovery depends too much on the functional attributes of Web services, we present a Web service selecting Broker model based on non-functional Web service quality QoS-ontology. Then we introduce the QoS Personal Preference Ratio (PPR) to quantify users' fuzzy preference, present QoS calculating formula and finally propose the QoS-based matchmaking algorithm based on the model.
