In this paper, we percent a Naïve Bayes model by taking into account the similarity in preferences (homophily) among the users and attributes of users (demographic) as a prior knowledge to enhance the prediction accuracy of collaborative filtering. Experiments are implemented on Movielens datasets 100K and 1M. The results show that the system can provide a recommendation in a best manner. ER -
