突发事件网络舆情信息扩散差异性度量与实证研究
Measurement and Empirical Research on the Difference in the Diffusion of Network Public Opinion Information in Emergencies
摘要
Abstract
[Purpose/Significance]There are differences in the diffusion of public opinion information between differ-ent emergencies and network platforms.This paper constructs a mathematical model to study the dissemination and diffusion mechanism of public opinion information,measures the differences in public opinion information diffusion,and provides theoretical support for precise governance of emergency network public opinion.[Method/Process]This paper focused on the general characteristics of public opinion information diffusion,considered the impact of different emergencies and net-work platforms on public opinion information diffusion,proposed the concept of public opinion information diffusion index,constructed a power-mapping based on measurement model for the difference in public opinion information diffusion on the network of emergencies,and studied the influence of parameters on public opinion information diffusion through numerical simulation.The validity and rationality of the model were verified by using the network public opinion cases data triggered by emergencies,and the effectiveness of the model for information diffusion prediction was verified by using multiple other cases.[Result/Conclusion]The difference of network public opinion information diffusion in emergencies could be meas-ured by the public opinion information diffusion index.The overall law of public opinion information diffusion is consistent.The influence of public opinion information diffusion index on public opinion information diffusion is not only reflected in the time dimension,but also reflected in the public opinion information volume dimension.关键词
