|Abstract:||The emergence of social media as a crucial paradigm has posed new challenges to the research and industry communities, where media are designed to be disseminated through social interaction. Recent literature has noted the generality of multiple features in the social media environment, such as textual, visual and user information. However, most of the studies employ only a relatively simple mechanism to merge the features rather than fully exploit feature correlation for social media applications. In this paper, we propose a novel approach to fusing multiple features and their correlations for similarity evaluation. Specifically, we first build a Feature Interaction Graph (FIG) by taking features as nodes and the correlations between them as edges. Then, we employ a probabilistic model based on Markov Random Field to describe the graph for similarity measure between multimedia objects. Using that, we design an efficient retrieval algorithm for large social media data. Further, we integrate temporal information into the probabilistic model for social media recommendation. We evaluate our approach using a large real-life corpus collected from Flickr, and the experimental results indicate the superiority of our proposed method over state-of-the-art techniques. © 2010 ACM.|
