This work proposes a new methodology for the Group Recommendation problem. In this approach we choose the Most Representative User (MRU) as the group medoid in a user space projection, and then generate recommendation based on his preferences. In the experiments, we evaluate our proposal along with other Group Recommendation strategies, taking two different measures from the area. We also discuss about properties shown by our strategy that provides robustness to problems inherent to interactions in group of users. Besides that, we developed the system Filmes em Grupo in order to obtain a dataset that bests suited experiments in the area.
