A QoS-based User Reputation Measurement Method for Web Services

Abstract

In Web services environment, high-quality services discovery and selection depend on reliable users with high reputations. However, user reputation is hard to accurately obtain directly. To evaluate the reliability of users, we present user reputation measurement method, named URMM. Based on the historical Quality of Service (QoS) values of users, we calculate user reputation value by the median and iteration operation. Based on real world public datasets, we conduct extensive experiments and demonstrate our proposed approach is more simple and effective than traditional approach.
