| Abstract: | This paper is based on the technology of topic detection and tracking theory to establish the topic model of vector space. To describe the evolution process and the trend of topics, this paper combined with the evolutionary theory of the life cycle to do the topic detection and tracking and measure topic intensity. It＇ s more convenient to find out the community dynamics by researching the trend of the community of Tibetan language. |
