An Improved Model of the Internet Public Opinion Spreading on Mass Emergencies

Abstract:

In the WEB2.0 environment, the report of public events will appear on the Internet as soon as they occur and attract a large number of peoples attention in a very short time. It is believed that the Internet public opinion represents the social public opinion. Hence, it is very valuable to study the relationship between the Internet public opinion and mass emergencies. In this paper, we proposed an improved effect model of the Internet public opinion spreading on mass emergencies. Different from the original model, we use variables as the parameters of the equation instead of constants and the whole mass emergency is divided into five stages. In the first two stages, the new participants proportion u(t) and the new leavers proportion v(t) holds the inequality u(t)≥v(t), and in the other stages, they hold u(t)≤v(t). Simulations show that the design of our proposed model can well fit the mass emergency development process.
