In the area of topic tracking, topic develops with time, traditional topic tracking method can tracking the relevance story efficiently.It can not know relationship between events occurred during the develop of topic.It can neither know the whole history of the topic tracking.This paper proposes a new method based on the calculation of the subtopic similarity.The method concern the time characteristic of the topic tracking and use it to manipulate the information.Experiment result shows that the method analysis the evolution history of the topic efficiently.
