英文摘要	The development of information technology brings numerous online news and events to our daily life. One big problem of such information explosion is, many times there are diverse descriptions for one incident which make people confused. Although previous researches have provided various algorithms to detect and track events, few of them focus on uncovering the diversified versions of an event. In this paper, we propose a novel algorithm which is capable of discovering different versions of one event according to the news reports. We map documents to the topic layer to get the information of each topic. Then we extract the highly-differentiated words of each topic to cluster the documents. Compared with previous work, the accuracy of our algorithm is much higher. Experiments conducted on two data sets show that our algorithm is effective and outperforms various related algorithms, including classical methods such as K-means and LDA. ? 2011 IEEE.; EI; 0
