Recommender systems play an important role in helping online users find relevant information by suggesting information of potential interest to them. Due to the potential value of social relations in recommender systems, social recommendation has attracted increasing attention in recent years. In this paper, we present a review of existing recommender systems and discuss some research directions. We begin by giving formal definitions of social recommendation and discuss the unique property of… 
A study on features of social recommender systems
TLDR
Different features of social networks that play a major role in generating effective recommendations are investigated and each feature plays an essential role in giving good recommendations and resolving the issues of traditional recommender systems.
A community driven social recommendation system
TLDR
This paper introduces community-wise social interactions as a new dimension for recommendations and presents a social recommendation system using collaborative filtering and community detection approaches, developed using map-reduce framework.
Personalized recommender system based on social relations
TLDR
This paper presents a novel recommender system that makes use of user's social relationships in two levels: computing the similarity between them and identifying user's neighbors set and the experimental results show that the proposed model outperforms Collaborative Filtering (CF) basedRecommender system in terms of recommendation accuracy.
Sentiment Analysis and User Similarity for Social Recommender System: An Experimental Study
TLDR
This paper proposes a social recommender system using memory based collaborative filtering models with user-oriented methods as basic models, in which an analysis on the correlations between social relations and user interest similarities is conducted.
Exploiting Social Information in Pairwise Preference Recommender System
TLDR
Social PrefRec is envisioned, a social recommender that applies user preference mining and clustering techniques to incorporate social information on the pairwise preference recommenders, based on the hypothesis that user's preference is similar to or influenced by their connected friends.
A review of social recommendation
TLDR
A review of the social recommendation system in recent years is presented, and the trust inference algorithm, recommended key technology and its application progress are compared and analyzed.
Recommender Systems with Characterized Social Regularization
TLDR
This paper presents a novel CSR (short for C haracterized S ocial R egularization) model by designing a universal regularization term for modeling variable social influence and demonstrates that CSR significantly outperforms state-of-the-art social recommendation methods.
Development of a group recommender application in a Social Network
Research Fronts of Robust Social Recommendation
TLDR
This paper proposes a framework for the research fronts of the robust social recommendation approaches that takes multidimensional relationships into consideration, and summarizes social recommendation shilling attack models based on the analysis of the relationships in social networks as well as the roles of relationships on recommendation.

Exploiting Local and Global Social Context for Recommendation
TLDR
Empirical results on real-world datasets demonstrate the effectiveness of the proposed framework LOCABAL and further experiments are conducted to understand how local and global social context work for the proposed Framework.
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.
Trust-Aware Recommender Systems
TLDR
This chapter gives an overview of state-of-theart recommender systems with a focus on trust-awareRecommender systems and describes the ways that trust information can help to improve the quality of the recommendations.
Social contextual recommendation
TLDR
This paper investigates social recommendation on the basis of psychology and sociology studies, which exhibit two important factors: individual preference and interpersonal influence, and proposes a novel probabilistic matrix factorization method to fuse them in latent spaces.
Improving Recommender Systems by Incorporating Social Contextual Information
TLDR
This article proposes a factor analysis approach based on probabilistic matrix factorization to alleviate the data sparsity and poor prediction accuracy problems by incorporating social contextual information, such as social networks and social tags.
A matrix factorization technique with trust propagation for recommendation in social networks
TLDR
A model-based approach for recommendation in social networks, employing matrix factorization techniques and incorporating the mechanism of trust propagation into the model demonstrates that modeling trust propagation leads to a substantial increase in recommendation accuracy, in particular for cold start users.
Recommender Systems - An Introduction
TLDR
An overview of approaches to developing state-of-the-art recommender systems, including current algorithmic approaches for generating personalized buying proposals, such as collaborative and content-based filtering, as well as more interactive and knowledge-based approaches.
Augmenting collaborative recommender by fusing explicit social relationships
TLDR
The role of two types of social relationships: membership and friendship are explored, while being fused with traditional CF (Collaborative Filtering) recommender methods in order to more accurately predict users’ interests and produce recommendations to them.
Introduction to social recommendation
TLDR
This tutorial will introduce Social Recommendation and elaborate on how the various characteristics and aspects are involved in the social platforms for collective intelligence in the context of theory and models of social networks.
A collaborative filtering framework for friends recommendation in social networks based on interaction intensity and adaptive user similarity
TLDR
An implicit rating model is designed, for estimating a user’s affinity toward his friends, which uncover the strength of relationship, utilizing both attribute similarity and user interaction intensity and a CF-based framework is proposed that offers list of friends to the user by leveraging on the preference of like-minded users.
