摘要：
In modern Internet life, the communication mechanism of public opinions is essential to master online mass behavior. This paper mainly studies the different influences of different individuals in online communication. Firstly, based on the crucial role that opinion leaders play in online communication, a SELOR model dividing the infectious individuals into leader infectious individuals and ordinary infectious individuals is constructed. Secondly, due to the difference in the number of contacts between leader ones and ordinary ones, a saturated contact rate is introduced to quantify their own influence. Finally, according to the impact of reversal in real life event, an event reversal factor is introduced. Through the simulation of real events, it is discovered that the modified model can better adapt to online communication than the traditional epidemic model.
