英文摘要：

This paper applies the method of decaying word co-occurrence graph to multi-document summarization. The algorithm of co-occurrence graph combines statistics with semantic dnalysis and tries to get subject-words of the cluster of multiple documents and linkage information of different text subjects. It optimizes sentence selection by using the idea of MMR so as to obtain summarization with coverage of the main content while least information redundancy. The experiment of DUC2005 evaluation shows that the result is satisfactory.
