网络已经成为人们日常生活中必不可少的发布和获取信息的渠道, 越来越多的消费者依靠网络获取突发事件的相关信息, 因此, 网络舆情在推动突发事件发展的过程中越来越重要。本文基于传染病模型理论, 构建了食品安全事件网络舆情传播演变中的模仿传染模型, 研究网民在食品安全事件网络舆情传播中的模仿传染机理和行为, 并以双汇"瘦肉精"事件为例, 对模型进行仿真以验证模型的正确性, 以期为食品安全事件利益相关者正确应对网络舆情演变过程中网民的传染行为提供决策参考。
Abstract
The network has become the daily essential channel to publish and access information for people, more and more consumers rely on network access to emergency events, so the network public opinion is becoming more and more important in the development process to promote the event. This article is based epidemic model theory to build an imitation and contagion model in the evolution of network public opinion on food safety incident, which aims to study the infection mechanism and behavior of the Internet users in the process of public opinion spread of food safety incidents. The study takes the "ShuanghuiClenbuterol" events for an example, simulates and verifies the correctness of the model. It is expected to provide a reference to the stakeholders of food safety incidents who will correctly respond to imitation and contagion behavior of Internet users in the process of the network public opinion evolution.
