Recommender systems with social regularization
TLDR
This paper proposes a matrix factorization framework with social regularization, which can be easily extended to incorporate other contextual information, like social tags, etc, and demonstrates that the approaches outperform other state-of-the-art methods.

SoRec: social recommendation using probabilistic matrix factorization
TLDR
A factor analysis approach based on probabilistic matrix factorization to solve the data sparsity and poor prediction accuracy problems by employing both users' social network information and rating records is proposed.

Learning to recommend with social trust ensemble
TLDR
This work proposes a novel probabilistic factor analysis framework, which naturally fuses the users' tastes and their trusted friends' favors together and coin the term Social Trust Ensemble to represent the formulation of the social trust restrictions on the recommender systems.

Fused Matrix Factorization with Geographical and Social Influence in Location-Based Social Networks
TLDR
This paper is the first to fuse MF with geographical and social influence for POI recommendation in LBSNs by capturing the geographical influence via modeling the probability of a user’s check-in on a location as a Multi-center Gaussian Model (MGM).

Where You Like to Go Next: Successive Point-of-Interest Recommendation
TLDR
This paper proposes a novel matrix factorization method, namely FPMC-LR, to embed the personalized Markov chains and the localized regions in the check-in sequence, and utilizes the information of localized regions to boost recommendation.
