They present additional tasks w.r.t. those for single users, such as the identification of the groups, or their modeling. While this clearly amplifies the possible reproducibility issues, to date, no framework to benchmark group recommender systems …

Specifically, the presence of collaborative and leader users leads the group to trust these users when a final decision has to be taken.
