A Study Of The Models Of Public Opinion And Mobile-telephones Short Message Infection Based On The Cellular Automaton

The public opinion refers to a rally on the public's suggestion, it is a foundation of the social behavior, can accelerate or hinder the settlement of the social concern. The public opinion is the evolution course of a typical social complicated system built-in property, the numerous and complicated form appears in its spread course. In the aspects of predicting the development trend of human society, relaxing and adjusting the relationship between various groups in society, and accelerating the social development, public opinion plays a very important role. Thus it is valuable to make researches on the infection of public opinion,especially the process of the infection and the characteristic of public opinion, and how to control it. On the basis that the existing public opinion studies we will perform dynamic simulation of the CA model, study the process of the infection and the characteristic of public opinion through the numerical simulation of the computer, and then strengthen the understanding the infection of public opinion in this paper.In chapter one we have introduced the value on studying the infection of public opinion, the characteristic and development of public opinion, complicated network theory, and have introduced mobile-telephones short message dissemination and the mechanism of cellular automaton.In chapter two we have studied the model of the audience's behaviors in stadium, and also discussed the evolvement changing of the model on its parameters.On the basis of public opinion model that Hacken has put forward, we establish cellular automaton Hacken public opinion model and discuss the influence that the environment and preference factor to the public opinion through the numerical simulation of the computer in chapter three. The sociologist believed that, human's public opinion behavior is the function that the people interact with the environment, people should survive in the certain social environment, and the innumerable individuals'opinion on one concrete event always follow the environment and other people's factors tend to and melt unanimously in particular time. And we have got the conclusions...
