基于IBU模型的信息传播

Information dissemination based on IBU model

考虑到发布信息用户的可信度差异对信息传播过程具有一定的影响,针对真假信息传播的广度和效果,提出了一个新的IBU模型,研究了信息内容真实性以及发布信息用户的可信度对信息传播动力学过程的影响。通过MATLAB仿真对该模型的传播效果进行实验,实验结果表明,无论发布信息用户的可信度有多大,与信息可信本身无关,只与信息内容本身是否可信有关;信息发布者可信度越大,对于信息传播的时间就越长;相反,信息发布者的可信度越低,传播时间越短,但并不会改变信息内容真假的性质。研究成果为相关职能部门在信息管控方面提供了理论基础。

Considering that the credibility difference of users of publishing information has certain influence on the information dissemination process,this paper proposed a new IBU model for the breadth and effect of true and false information dissemination,and it studied the effects of the authenticity of information content and the credibility of users who forward information on the dynamic process of information dissemination.It tested the propagation effect of the model by MATLAB simulation.The experimental results show that no matter the credibility of the user who publishes the information,it has nothing to do with the credibility of the information itself,only related to whether the information content itself is credible;the larger the credibility of the information publisher,the longer the information transmission time;on the contrary,the lower the credibility of the information publisher,the shorter the propagation time,but it does not change the true and false nature of the information content.The research results provide a theoretical basis for relevant functional departments in information management and control.
