Abstract—Personalized recommendation systems can help people find things that interest them and are widely used in developing the Internet or e-commerce. Collaborative filtering (CF) seems to be the most popular technique in recommender systems. However, CF is weak in the process of finding similar users. To resolve these problems, trust-aware recommender systems (TaRSs) have been developed in recent years. In this study, we propose a new approach that incorporates the content of reviews in a TaRS. In addition, we use a new dataset that is collected from the Yahoo!Movie website, whereas traditional research has used Epinions or Movielens. Finally, we evaluate the experiment results using precision and coverage.
Index Terms—Collaborative filtering, content of reviews, trust network, Yahoo!Movie dataset.
