Research on the evolution and influence in society's information networks based on Grey Model

In order to explore the evolution of society information network and its influence to the public in the future, this paper use the improved Cycle Model of Information Flow to explore the flow of information. Taking the news which is selected by News Selection Model as an example, combining with Grey Model and Time Series Forecast Model, the paper forecast the development of society information network and analyze the society information network's influence to public in the future. At last, we use Kermach-Mchendrick Model to discuss the influence of information network topology's way and intensity to the information transmission and public's views. We get the result that the topology's way can improve the speed of information transmission and public's views change, and the topology intensity stronger, the effect faster and more obvious.
