From Group Recommendations to Group Formation
Summary: Framework for forming user groups to maximize satisfaction under LM/AV semantics for group top-k recommendations. Shows NP-hardness of optimal group formation; provides two efficient LM algorithms with bounded absolute error and scalable AV heuristics, validated on large real datasets.
