Collaborative Filtering with Entity Similarity Regularization in Heterogeneous Information Networks

  title={Collaborative Filtering with Entity Similarity Regularization in Heterogeneous Information Networks},
  author={Xiao Yu and Xiang Ren and Quanquan Gu and Yizhou Sun and Jiawei Han},
Researchers have been studying hybrid recommender systems which combine user-item rating data with external information in recent years. Some studies suggest that by leveraging additional user and / or item relations, e.g., social network, the performance of the recommendation models can be improved. These studies, nevertheless, mostly utilize a single type of external relationship. Considering the heterogeneity of real-world applications, we propose to position the well-studied recommendation… CONTINUE READING
