As many online systems rely on user ratings for making decisions such as recommendations, the quality of such rating scores are increasingly important. On the other hand, users interact with each other via online communities. How such interactions affect the trueness of their ratings? Can we obtain the true rating scores that exclude the influences among users? This paper presents a conceptual framework that characterizes the influences on quality of services among users, and an algorithm that estimates the true rating scores by minimizing the influence among users. In other words, the influence on users' ratings due to their interactions is minimized so as to obtain the more accurate rating scores. The proposed approach has been validated by experimenting on real data sets. The results of the experiments have demonstrated that our approach is capable of estimating true ratings.

Conference2016 IEEE Symposium Series on Computational Intelligence
OtherThe 2016 IEEE Symposium Series on Computational Intelligence (IEEE SSCI 2016) will be held in Athens, Greece, a city full of arts, philosophy and historical attractions. SSCI is a flagship annual international conference on computational intelligence sponsored by the IEEE Computational Intelligence Society, promoting all aspects of theory, algorithm design, applications and related emerging techniques . As a tradition, IEEE SSCI 2016 will co-locate a large number of exciting symposiums , each dedicated to a special topic within or related to computational intelligence, thereby providing a unique platform for promoting cross-fertilization and collaboration. SSCI 2016 will be featured by cross-symposium tutorials, keynote speeches, panel discussions, PhD consortiums, oral presentations and poster sessions. Student grants, Best paper Awards and Student Best Paper Award will be given.
