| Abstract: | With the development of the Internet,a new kind of event is emerging.Researchers call them "new media event",which has great social influence.Compared with the traditional media events,the new media events enable the grass-roots not only have the right to know the events,but also have the power to change the course of events.So many researchers consider that the new media can settle disputes between the government and the public.In conclusion,research on the emerging mechanism and communication rules of the new media events is significant.In this paper,from the concepts and differences of "media event" and "new media event".We summarize the communication rules of the new media event,build the model from the perspective of number of topics.Finally,we find out the key value—query degree,which shows the great impact on number of topics. |
