This paper proposes a Latent Document Similarity Model(LDSM).It denotes each document pair as a bipartite graph,where each node is a latent topic,and each edge is weighted with the similarity between the corresponding topics,and it represents the document similarity as the optimal matching of the bipartite graph.Experimental results show that LDSM outperforms the document similarity model based on TextTiling and the optimal matching of bipartite graph at both average precision and average recall.
