ABSTRACT
Recommender system plays a vital role in e-commerce business by providing personalized product recommendation. However, most of the existing recommender system are accuracy-centric and biases on recommending popular items. However, recommending relevant long tail items is another research challenge in recommendation community. In this article, we propose a graph based approach to enhance the long tail items in recommendation. The preliminary results are very encouraging on standard rating dataset. Proposed approach outperforms recently introduced recommender systems which focus on long tail item recommendation.

Long-tail Session-based Recommendation
RecSys '20: Proceedings of the 14th ACM Conference on Recommender SystemsSession-based recommendation focuses on the prediction of user actions based on anonymous sessions and is a necessary method in the lack of user historical data. However, none of the existing session-based recommendation methods explicitly takes the ...
