一种QoS感知的Web服务群体评价方法
QoS-aware group evaluation method of Web services
摘要
Abstract
The traditional QoS-aware Web services selection methods need accurate weights given by the users to empress their preferences over different QoS properties. A QoS-aware Web service group evaluation method is proposed to solve the problem of service selection of the users whose preferences are indeterminate. This paper analyses the necessity of Web services group evaluation in detail. Then it gathers the historical selection results of the users who have explicit preferences to obtain the group evaluation of Web services by Condorcet and Borda function of group decision-making theory. Thus, user who has no specific QoS preference can select services referring to the evaluation result. The theoretical analysis and simulation experiment validate rationality and availability of the Web services evaluation method.关键词
