摘要： 针对现有的基于QoS的度量方法只考虑对Web service的公共属性的研究,忽略了领域属性,不具备通用性的问题,把QoS度量分为有约束和无约束两类,并分别提出QoS度量方法.对有约束的QoS度量,提出一个基于约束信息的度量方法;对于无约束QoS度量,给出一种通过对已有服务使用信息、自动调整QoS度量的指标及指标系数的方法.最后,介绍算法的实现平台及实验结果分析,并通过实验证明方法的可行性和有效性.

Abstract: The existing measuring methods of QoS lack versatility because they only take the common attributes of Web service into consideration but neglect the domain attributes. The measurements of QoS are therefore divided into two categories, i.e., the constrained Web service and unconstrained one with their respective measuring methods proposed. For the constrained QoS measurement, an algorithm based on constrained information is proposed. As for the unconstrained QoS measurement, the proposed algorithm can adjust automatically the QoS indices and its corresponding coefficients through analyzing service using information. The implemented platform and analysis of experimental results are provided, with which the applicability and effectiveness of the method proposed are verified.
