摘要:
In this study, we developed a way to increase recommendation effectiveness by incorporating social network information into CF. We collected data about users’ preference ratings and their social network relationships from a social networking Web site. Then, we evaluated CF performance with diverse neighbor groups combining groups of friends and nearest neighbors. Our results indicated that more accurate prediction algorithms can be produced by incorporating social network information into CF.
