Group Recommender Systems Based on Members' Preference for Trusted Social Networks

Xiangshi Wang, Lei Su, Qihang Zhou, Liping Wu
2020 Security and Communication Networks  
The focus of this paper is group recommendation based on an average strategy, where group members have preferential differences and use trusted social networks to correct for their preferences.  ...  However, group members' preferences are not fully considered in group recommendations, and how to use trusted social networks based on their preferences remains unclear.  ...  implicit feedback dataset average strategy; and IFpre (G, i) (implicit feedback prediction) indicates a group recommendation based on the implicit feedback of dataset member preferences by trusted social  ...

SURVEY ON RECOMMENDER SYSTEMS FOR SOLVING COLD START PROBLEM

Naveena M, Shivakumar N
2019 International Journal of Recent Trends in Engineering and Research  
The task of recommender system is to predict the user's ratings for each item and ranking the items. In research area RS plays a major role.  ...  For example, the ratings are very high for the most popular items and some items are rated without considering the knowledge in utilizing it.  ...  The intelligence of social relation of a user together with the information of ratings is used by the social recommender system for providing recommendations [22] .  ...

Factored similarity models with social trust for top-N item recommendation

Guibing Guo, Jie Zhang, Feida Zhu, Xingwei Wang
2017 Knowledge-Based Systems  
In this article, we propose three factored similarity models with the incorporation of social trust for item recommendation based on implicit user feedback.  ...  Trust-aware recommender systems have attracted much attention recently due to the prevalence of social networks.  ...  Although many studies have been conducted on the top-N recommender systems on the basis of implicit user feedback, very few have incorporated social trust relationships for item recommendation.  ...

Relational Metric Learning with Dual Graph Attention Networks for Social Recommendation [chapter]

Xiaodong Wang, Zhen Liu, Nana Wang, Wentao Fan
2020 Lecture Notes in Computer Science  
Specifically, relations in two domains are modeled as two types of relation vectors, with which each user can be regarded as being translated to both multiple item-aware and social-aware representations  ...  Existing social recommenders typically incorporate all social relations into user preference modeling, while social connections are not always built on common interests.  ...  Recently, top-N recommendation based on implicit feedback has attracted much research interest since implicit feedback is much more abundant and easier to collect in practice [10] .  ...

Trust and Trustworthiness in Social Recommender Systems [article]

Taha Hassan, D. Scott McCrickard
2019 arXiv   pre-print
Ranking algorithms for social recommendation often encode broad assumptions about network structure (like homophily) and group cognition (like, social action is largely imitative).  ...  The constituent dimensions of trustworthiness (diversity, transparency, explainability, disruption) highlight new opportunities for discouraging dogmatization and building decision-aware, transparent news  ...  FUTURE WORK This study explores the theoretical foundations of trust-aware ranking in social recommenders.  ...

SPMC: Socially-Aware Personalized Markov Chains for Sparse Sequential Recommendation

Chenwei Cai, Ruining He, Julian McAuley
2017 Proceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence  
Dealing with sparse, long-tailed datasets, and cold-start problems is always a challenge for recommender systems.  ...  In this paper, we propose new methods to combine both social and sequential information simultaneously, in order to further improve recommendation performance.  ...  In addition to the feedback itself, we assume that timestamps are also available for each action, as well as the social relations (or trust relationships) of each user.  ...

implicit influence of trusted users on the prediction of items for an active user.  ...  By analyzing the social trust data from four real-world data sets, we conclude that not only the explicit but also the implicit influence of both ratings and trust should be taken into consideration in  ...  LITERATURE SURVEY Trust-aware recommender systems have been studied because social trust provides an alternative view of user preferences other than item ratings.  ...
