Abstract: Story link detection is a task of topic detection and tracking, which is to detect whether two stories arc "linked",or discuss the same event This paper proposed a story link detection method based on the dynamic extraction of correlative word. Correlative word is defined to be a pair of words that satisfy certain Relation Restriction. In this paper, relation restriction refers to a set of features. hhis paper explored three features, which include the initial letter, locanon and window. The more two stories had the same correlative words, the larger similarity they had. Experimental results showed that the story link detection method based on the dynamic extraction of correlative word performs very well, which testifies the great capabilities of this method. We also find that relation restriction is critical to the performance of this method.
