摘要:

为研究谣言扩散的规律,采取有效措施减小谣言对社会的影响,根据社会认同原理抽象并量化个体的2种重要行为——引导行为和模仿行为。对Bass模型进行改进,构建Bass-SI谣言扩散模型,同时对谣言在该模型上的传播特性进行Mathematica仿真,分析行为强度和行 为稳定度对谣言扩散过程的影响,并提出相应的抑制措施。研究结果表明:引导行为决定谣言扩散过程前期变化趋势,行为强度越大,稳定度越低,谣言扩散程度越大;模仿行为对谣言扩散过程后期影响较大,行为强度越大,稳定度越高,谣言扩散程度越大。

Abstract:

In order to research the law of rumor spreading and take effective measures to reduce the impact of rumor,according to the principle of social identity,this paper abstracts and quantifies two important behaviors:guiding behavior and imitating behavior.It improves the Bass model,proposes Bass-SI model about rumor diffusion and makes the simulation under Mathematica for the propagation property of the rumor.At the same time,it analyzes the impact of behavioral intensity and behavioral stability on rumor spreading process and proposes the restrain measures.It finds the following conclusion:the guidance behavior determines the early trend of the rumor diffusion process,if the intensity of behavior increases and the stability decreases,the degree of rumor diffusion will increase;the imitating behavior has an important influence on the latter process of rumor diffusion,if the intensity of behavior increases and the stability increases,the degree of rumor diffusion will increase.

Key words: rumor spreading, social identity, Bass model, propagation property, Mathematica simulation
