Link prediction in bipartite graphs using internal links and weighted projection

Oussama Allali, Clémence Magnien and Matthieu Latapy

Many real-world complex networks, like client-product or file-provider relations, have a bipartite nature and evolve during time. Predicting links that will appear in them is one of the main approach to understand their dynamics. Only few works address the bipartite case, though, despite its high practical interest and the specific challenges it raises. We define in this paper the notion of internal links in bipartite graphs and propose a link prediction method based on them. We describe the method and experimentally compare it to a basic collaborative filtering approach. We present results obtained for two typical practical cases. We reach the conclusion that our method performs very well, and that internal links play an important role in bipartite graphs and their dynamics.

Link prediction in a file-provider network

Link prediction in a file-provider network

> By Oussama Allali, Matthieu Latapy and Clémence Magnien Link prediction is a key research problem within the analysis of network dynamics. It aims at predicting the links which will appear in future evolution of the network. We consider here a set of peers and files, where each peer is linked to the files it […]
