Abstract：With the development of Web 2.0, social tagging systems, such as Flickr, become more and more popular. As a new developed user community, Flickr group not only attracts tens of thousands of online users to participate, but also becomes one of the research hotspot in recent years. In this paper, a topicoriented photo browsing method is proposed to deal with the photo browsing problems in Flickr groups which lack of clear themes. The proposed method consists of three main steps: matrix space representation of phototag relations, nonnegative matrix factorization based photo topic finding and a computational model of photo influence strength. The experiments on Flickr dataset show the proposed method is useful and effective.
