本文采用元胞自动机理论进行政务微博危机信息扩散的研究,设计了政务微博元胞自动机模型。通过定义用户倾向度、用户受领域影响程度以及用户转发意愿,设计了符合政务微博的元胞演化规则。并进一步利用MATLAB进行仿真,通过对比真实数据,证实了模型的有效性,讨论不同消息质量对危机扩散的影响。 In this paper, the use of cellular automata theory of micro-Bo government information dissemination of crisis research, design of government microblogging cellular automaton model. Through the definition of user tendencies, the extent of users affected by the field and the user’s willingness to forward, a cellular evolution rule that conforms to the government microblog is designed. And further use MATLAB to simulate. By comparing the real data, the validity of the model is verified, and the influence of different message quality on crisis spread is discussed.
