In summary, our method clearly outperforms matrix factorization for recommendation (both PMF and BPMF) in terms of coverage because of exploiting the trust-network.
Other algorithms based matrix factorization have been proposed for recommendation, which assume that the preference of a user can be represented by a small number of unobserved features, such as probabilistic matrix factorization (PMF) [12], variational Bayesian matrix factorization (VBMF) [34], Bayesian probabilistic matrix factorization (BPMF) [13], and general probabilistic matrix factorization (GPMF) [35].
