考虑信息真伪的食品安全网络舆情传播仿真与管理对策研究

Food safety internet public opinion transmission simulation and management countermeasures considering information authenticity

食品安全网络舆情对于食品安全管理具有重要意义.本文针对食品安全网络舆情的特点,在考虑信息的真实性、网民的信息甄别能力、网民对信息传播主体的信任程度等因素的基础上,运用MATLAB软件对舆情的传播过程进行模拟仿真研究,探讨食品安全网络舆情的传播机理.研究结果表明,可以通过减少信息发布节点、集中发布食品安全网络信息,以及加强食品安全知识宣传与培训、提高公众的食品安全信息甄别能力,以提高真实性较高的食品安全网络信息在舆情中的传播概率.

Food safety internet public opinion has important significance for food safety management. In this paper, according to the characteristics of food safety internet public opinion, using MATLAB software to simulate the transmission process of public opinion on the basis of considering the authenticity of information, the information identify capability of netizen, the degree of trust of netizen on the ones who transmission information and so on, and investigate the transmission mechanism of food safety internet public opinion. The results show that, we can increase the transmission probability of food safety network information which have higher authenticity in public opinion by reducing information publishing node and centralized publish food safety network information, as well as enhancing food safety knowledge publicity and training and improving the public＇s capability of identify food safety information.
