Research On The Evolution Of The Network Public Opinion Of The Emergency In Colleges

With the development of the network, the emergency in colleges caused public opinion become a new topic in recent years, researching on the characteristics and evolution of public opinion network propagation stage, thus effectively guiding reduce the negative impact of network public opinion, and bring theoretical and practical value. Network public opinion of the emergency in colleges are divided into normal state and abnormal state in both cases with a criterion of the properties and impacts for the events and the difficulty dealing with events. An empirical analysis of two types of a representative case of "Fudan poisoning" and "Xiamen University doctoral case, explore the propagation process of the network public opinion of the emergency in colleges. In theory, combined with qualitative and quantitative research methods, explore the evolution of the various stages of the model of the propagation of the law, comb and improve the relevant theory. In fact, it can master the dissemination characteristics of the network public opinion of university emergency in two states, improve the crisis early warning mechanism, so that universities can deal with the multi state emergencies in the future effectively.Based on the analysis of domestic and foreign references, "Fudan poisoning" and "Xiamen University doctoral case" of two kinds of emergency in colleges are researched with literature analysis method, case analysis method, comparative analysis, scenario analysis. From the quantitative and qualitative point of view, the process of the evolution of the network public opinion dissemination of university emergencies could be researched. Firstly, it introduces the concept and characteristics of emergency in colleges, and summarizes the differences between the two states of the network public opinion of emergency in colleges. Secondly, based on the dynamic mean field equations, according to the characteristics of different stages of network public opinion, the model parameters are assigned different values, establishing the simulation model of dissemination of various stages for network public opinion with the MATLAB software. Analysising the trend of network public opinion in three different development stages, model characteristics and evolution of the law, and discussing the simulation results based in MATLAB. In the case of empirical research, looking for a representative platform for data mining in the public opinion media platform and personal media platform, collecting the data about amount of network public opinion, analyzing three stages. Then confirm the validity of the model with the MATLAB graphics. Finally, through the empirical analysis conclusion, changing model parameters setting, it concluded the comparison chart with changing path model. On this basis, it is concluded that the information characteristics of the spread of the network public opinion, and put forward the control measure and suggestion about the spread of the network public opinion of the emergency in colleges.
