SibRank: Signed Bipartite Network Analysis for Neighbor-based Collaborative Ranking

Bita Shams,Saman Haratizadeh

Published 2016 in arXiv.org

ABSTRACT

Collaborative ranking is an emerging field of recommender systems that utilizes users’ preference data rather than rating values. Unfortunately, neighbor-based collaborative ranking has gained little attention despite its more flexibility and justifiability. This paper proposes a novel framework, called SibRank that seeks to improve the state of the art neighbor-based collaborative ranking methods. SibRank represents users’ preferences as a signed bipartite network, and finds similar users, through a novel personalized ranking algorithm in signed networks.
