摘　　要：根据网络信息传播与传染病传播的相似性,用SIR模型对网络信息传播进行预测,并且考虑到传染病模型中的“传染因子”一般为常数的局限性,利用网络信息热度对传播的影响,对传染因子进行修正,保证热度更高的信息得到更多传播,从而提高模型准确性。最后利用“wordle”网站的数据进行检验,证明了模型的有效性。Based on the similarity between network information dissemination and infectious disease dissemination,the SIR model is used to predict the network information dissemination.Recognizing the limitation of a constant"infection factor"in infectious diseases,we modify it as a variable according to the influence of network information popularity to ensure that higher popular information will be disseminated more,thus improving the accuracy of the model.The validity of the model is tested using data from the"wordle"website.
