In this paper, we present a novel approach that models the mutual reinforcing relationship among papers, authors and publication venues with due cognizance of publication time. We further integrate bookmark information which models the relationship between users’ expertise and papers’ quality into the composite citation network using random walk with restart framework. The experimental results ...
