改进的微博传播模型的影响因素分析

Factors Analysis for Improved Information Dissemination Model on Microblog

摘要: 微博作为社会网络信息传播的热门平台，对舆论传播与监督具有重要作用。本文基于经典SIR 传播模型，以微博信息在易传播者、传播者和沉默者之间的状态转换为基础，建立了基于认证用户和绝对沉默者的微博网络传播模型，并通过仿真分析了微博传播的影响因素。研究表明认证用户节点和普通节点的传播率越高，停止传播率越低或者绝对沉默率越高，则微博信息传播达到稳定状态越快，对实际控制社交平台的信息传播具有一定的理论分析依据和实践指导意义。

Abstract: Microblog is a popular platform for the information dissemination of social networks, which plays an important role for communication and supervision of public voice. Based on the classic SIR model and the process of microblog information dissemination on the state transformation between user nodes, including easy disseminators, disseminators and silencers, the improved microblog dissemination model with certified users and absolute silencers was built. The factors affecting the spread of microblog information were analyzed and simulated. Researches show that the higher the transmission rate of authenticated users and the normal nodes, the lower the stop transmission rate, and the higher the rate of absolute silence, the sooner time to reach steady state of the microblog information dissemination. It has some theoretical basis and practical significance for actually controlling information dissemination of the popular social platform.
