基于SEIR模型的网络视频用户信息茧房动态演化研究

Research on Dynamic Evolution of Internet Video Users’Information Cocoons Based on SEIR Model

[目的/意义]为探究网络视频用户不同层次信息茧间的演化规律,找出演化过程中的关键环节,预防网络视频用户信息茧房问题的产生和扩散,保持网络视频用户信息生态的和谐稳定。[方法/过程]基于经典传染病SEIR模型构建了网络视频用户信息茧房动态演化模型,就各状态间的转移率变化对系统免疫过程的影响进行了仿真实验。[结果/结论]降低系统中易感者感染率或轻症者重症率可以缩减患者密度,干预措施的适时介入能使得系统内视频用户信息茧房问题得到有效控制。此外,控制信息茧房问题蔓延的根本在于提高个体自身免疫能力。

[Purpose/significance] The paper aims to explore the evolution law between different levels of the information cocoon of Internet video users,find out the key links in the evolution process,prevent the occurrence and spread of the problem of Internet video users’ information cocoons,and maintain the harmony and stability of Internet video users’ information ecology. [Method/process] Based on the classic infectious disease SEIR model,the dynamic evolution model of the Internet video users’ information cocoons is constructed,and the simulation experiment is carried out on the influence of the change of the transition rate between the effects on the systemic immune process. [Result/conclusion] The research results show that reducing the infection rate of susceptible persons or the severe rate of mild persons in the system can reduce the maximum scale of patient density,and timely intervention measures can effectively control the information cocoon problem of video users in the system. In addition,the root of controlling the spread of the information cocoon problem is to improve the individual’s autoimmune ability.
