Abstract—In recent years, there are widely used online stores on the Internet which have customer review facilities. Although these reviews help users decide their actions, there are incredible, fake or irresponsible reviews in general. It is difficult for site users and site managers to evaluate the credibility of reviews and reviewers. In this paper, we show the method to quantify the credibility of review scores and to find out credible reviewers and credible review scores based on a bipartite relation between reviewers and sale items. We also show the experimental results on the travel website. Through our experiments, we discuss these indexes for reviewers and sale items are also effective for the future prediction of review scores.
Index Terms—Credibility, user review, travel website, HITS algorithm.
