Item Group Recommendation

Limeng Zhang, Rui Zhou, Haixin Jiang, Hua Wang, Yanchun Zhang
2017 Proceedings of the 26th International Conference on World Wide Web Companion - WWW '17 Companion  
In this paper, we focus on recommending an item set to multiple users. Group recommender systems are designed to deal with the issue of recommending items for a user group.  ...  Specifically, we evaluate each consumer's preference to an item group from two perspectives, attraction part from the customer herself and social affection from her friends.  ...  In recent years, user-based group recommender systems attract more researches in modeling group preference with some new methods.  ...

Group recommendation

Sihem Amer-Yahia, Senjuti Basu Roy, Ashish Chawlat, Gautam Das, Cong Yu
2009 Proceedings of the VLDB Endowment  
Single user recommendation has received significant attention in the past due to its extensive use in Amazon and Netflix.  ...  In this paper, we analyze the desiderata of group recommendation and propose a formal semantics that accounts for both item relevance to a group and disagreements among group members.  ...  CONCLUSION Group recommendation is becoming increasingly important as people engage in social activities on the Web.  ...
