Abstract

Aiming at the unreasonable allocation of resource in the recommendation algorithm of bipartite network, and in order to enrich the diversity of recommended results and promote the recommendation of unpopular items, this paper proposed the algorithm for bipartite graph network structure, which used differential path weight to change resource delivery. It changed the first stage of resource transfer rules by user similarity to construct path weights and made the resources flow more towards the user nodes similar to the target users. Through the consideration of constructing path weight of the articles attributes' similarity, the second stage resources were more likely to flow to the objects which had similar attributes with the target users' purchased products. Experimental results show that the proposed algorithm improves the combination property of recommendation, and better solves the related problems in recommendation, which outperforms other popular network structure algorithms.
