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 attracts tens of thousands of online users to participate and becomes one of the research hotspot in recent years. In this paper, a topic-oriented 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 photo-tag relations, non-negative matrix factorization based photo topic finding and a computational model of photo influence strength. The experimental results on Flickr dataset show the proposed method is useful and effective.
