Abstract:

Online crisis happens so frequently that many researchers and experts have developed various models to explore information propagation mechanism. Existing information propagation models were mainly based on epidemiology or some features affected information propagation. However, few models considered the influence from neighbors or user's own resistance, which had influence on information propagation. These factors are discussed in this paper and they are(1) influence from neighbors, (2) user's own resistance, and (3) outside environment. The information propagation cellular automata model is developed in this paper to study information propagation and intervention mechanism based on these factors. Their impacts on information propagation and intervention are analyzed. The study is classified into two stages:information diffusion stage and information intervention stage. More attention is paid to the impact of intervention intensity and intervention time on the information propagation. Some inspirations are drawn based on analysis on the impacts of these factors on information controlling to support government online crisis response.
