In this paper, we try to give a solution to this problem based on homophily in social networks: we can use social networks' information in or-der to fill the gap existing in cold-start problem and find similarities between users. In this study, we use communi-ties, extracted from different dimensions of social networks, to capture the similarities of these different dimensions and accordingly, help recommendation systems to work based on the found latent similarities. By different dimensions, we mean friendship network, item similarity network, com-menting network and etc.
