Abstract :
Event evolvement and topic shifting can affect the accuracy of event tracking. A dual-center event model is proposed to improve the event tracking process by adjust the some attributes of event dynamically. The detail of maintenance of the model is given. The experiment results show that the dual-center event can improve event tracking effectively under the condition of event evolvement and topic shifting.
