Traditional topic tracking method can tracking the relevance story efficiently.But can't know relationship between events occurred during the develop of topic.This paper proposed a new method based on the multi-vector event model.The method constructed event based on similarity between subtopics and utilized the multi-vector model to find relation between events.In the experiment using practical data,The method analyzed the evolution history of the topic efficiently.
