| Abstract: | Purpose/Significance］The mathematical model was constructed to study the modeling and prediction of network topic dissemination law,in order to provide theoretical references for further research on the dissemination law of network topic.Method/Process］This paper qualitatively analyzed the characteristics of big data,quantifiability,measurable periodicity,predictability and other characteristics of network topic dissemination.Through the analysis of network topic dissemination mechanism,the normal model and derivative model of network topic dissemination law were constructed.The general method of dividing the stages of network topic dissemination was put forward and the trend prediction of network topic dissemination was studied.Result/Conclusion］Through empirical analysis of microblog topic data of"haze",the dissemination stages could be well divided and the dissemination trend could be predicted.Therefore,it was feasible to study the network topic dissemination law based on the mathematical model established in this paper. |
