Abstract
Subtopic is the division for a topic again, and it is a novel research direction compared with topic. Subtopic identification is the foundation for analysis of topic evolution relations. In this paper, we propose a novel method of Chinese story subtopic identification incorporating content and time features. We focus on analysis of subtopic content features of the story, and study the computation of subtopic word weights, the dimension reduction of subtopic words and the extraction of subtopic names. Five topics including 20 subtopics are used to implement the experiment. Experimental results show that the performance of the method proposed is better than the existing subtopic identification methods.
