An approach for cross-media retrieval with cross-reference graph and PageRank

In this paper, we propose a novel cross-media retrieval method. The most important feature of it is to integrate the multi-modal data seamlessly via a cross-reference graph, and then based on the graph, it is able to use improved personalized PageRank to calculate how close the media object associates with the query on semantic and content level. It is also able to adjust the cross-reference graph according to user´s relevance feedback, which refines the semantic relationship between the media objects, so as to improve the retrieval accuracy progressively. As demonstrated by the experiments, our method achieves satisfactory retrieval efficiency on multi-modal datasets
