Our system to KBA Track at TREC2012 is described in this paper, which includes preprocessing, index building, relevance feedback and similarity calculation. In particular, the Jaccard coefficient was applied to calculate the similarities between documents. We also show the evaluation results for our team and the comparison with the best and median evaluations.
