Abstract: Friend recommendation is an important recommender application in social media. Major social websites such as Twitter and Facebook are all capable of recommending friends to individuals. However, friend recommendation is a difficult task and most social websites use simple friend recommendation algorithms such as similarity and popularity, whose level of accuracy does not satisfy the majority of users. The difficulty of friend recommendation lies on the noisy environment of social network and the multi-dimensional social information. To overcome the problem, in this paper we propose a two-stage procedure for more accurate friend recommendation: In the first stage, based on the relationship of different social networks, the Flickr tag network and contact network are aligned to generate a ``possible friend list‘‘; Then, by making the assumption that ``a friend‘s friends also tend to be friends‘‘, we enlarge this list and in the second stage, a co-clustering algorithm is applied to the tag and image information of the list to refine the recommendation result in the first stage. Experimental results show that the proposed two-stage method achieves better and more acceptable recommendations.
