S Kalepu, S Krishnaswamy, SW Loke, Verity: a QoS metric for selecting web services and providers (gs:56), Web Information Systems Engineering Workshops, 2003
这篇是较早讨论 reputation for web service/service provider的论文之一.
作者提出
Reputation = <user rating, compliance, verity>
as a more intuitive indicator of the provider's trustworthiness
user rating: 用户的主观评分的平均值
compliance: 是SLA中规定的QoS值与实际QoS值的差正则化处理后的平均值
verity: compliance值的方差
从粒度上来讲, 分为SLA parameter, web service, service provider
从范围上来讲, 分为local(从某个用户的角度来评估)与global(从全局来评估)
这篇文章中提到的评估方法比较简单, 都是一些加加减减, 求求平均值, 也没有验证实际应用情况.
虽然现在来看没有什么特别的东西, 但是由于写的比较早, 被引用得还比较多, 因此还是稍微了解一下.
