摘要
基于用户偏好的Web服务选择能够增进用户与服务之间的交互,是面向个人化服务选择研究的重点。文中给出了值偏好的概念,提出了一个基于用户混合偏好的Web服务选择方法。该方法综合考虑用户对QoS属性的值偏好和权重偏好,定义多属性类型QoS模型V-QoS,并计算候选服务与用户值偏好的匹配度获得决策矩阵,结合权重偏好,采用多属性决策之逼近理想解法(TOPSIS)综合评价候选服务对用户偏好的匹配度,并以此作为服务选择的依据。最后通过对比实验证明了方法的有效性。
Web services selection based on user preferences, which can enhance the interaction between user and services, is the focus of personal oriented services selection study. Propose the concept of value preference which can express value restrictions on QoS properties, propose a service selection approach based on user＇s preferences, and the weight preferences and decision-making matrix formed by cal- culating the matching degree between candidate services and user＇s value preferences are used by multi-attribute decision-making meth- od, that is, technique for the order the preference by similarity to ideal the solution （ TOPSIS ）, which evaluates the match degree between candidate services and User preference and selects best service for user. Finally, Comparison experiment proves the validity of this method.
