Abstract Aiming at the friend recommendation in online social networks, this paper tries to fuse multiple social networks into one mixed graph on which the random walk with restart is implemented to provide personalized friend recomendation for users. The different roles of these networks are adjusted by parameters. Experiment demonstrates that this algorithm can improve the accuracy of friend recommendation in online social networks.
