低活跃度背景下的微博社区信息传播模型研究

摘要

Based on SIR model of fundamental dynamics, two characteristics of low activity and credibility were used to construct the informational dissemination model of micro-blog community.By crawling micro-blog data and calculating and simulating by Matlab, the law of information dissemination of micro-blog community was well described and tendency of information transmission was effectively predicted.%在SIR传染病模型所提供的基本动力学机制基础上，引入微博社区的低活跃度特征和可信度函数，构建微博社区信息传播模型，提出各个参数的计算方法，并在此基础上通过爬取微博数据、利用Matlab进行计算和仿真，可以很好地描绘微博社区的信息传播规律，并对信息传播趋势做出有效预测。
