Exploiting different users' interactions for profiles enrichment in recommender systems

User profiling is an important aspect of recommender systems. It models users' preferences and is used to assess an item's relevance to a particular user. In this paper we propose a profiling approach which describes and enriches the users' preferences using multiple types of interactions. We show in our experiments that the enriched version of users' profiles is able to provide better recommendations.São Paulo Research Foundation (FAPESP) (grants 2013/18698-4 and 2013/22547-1)CNPq (grant 304137/2013-8
