Group recommendations with rank aggregation and collaborative filtering
Linas Baltrunas, Tadas Makcinskas, Francesco Ricci⋆ · 2010
The majority of recommender systems are designed to make recommendations for individual users. However, in some circumstances the items to be selected are not intended for personal usage but for a group; e.g., a DVD could be watched by a group of friends. In order to generate effective recommendations for a group the system must satisfy, as much as possible, the individual preferences of the group's members.
