Research and Application of Online Public Opinion Early Warning Based on Emergency Epidemic Situation

This is an online public opinion early warning system in the case of epidemic emergencies. Due to public health emergencies in the past two years, these are related to people’s health and interfere with people’s life and work. A variety of voices have emerged on various communication platforms, even causing online public opinions and disturbing social order. In the study of the network public opinion early warning system, the characteristics and requirements of the network public opinion are firstly developed to build the early warning system architecture, and then the functional module, monitoring module, analysis module and evaluation module are developed. Finally, the experimental verification is adopted. Research shows that online public opinion can be quickly controlled or guided in view of the epidemic. Therefore, the development of an online public opinion early warning system based on an outbreak situation is reasonable and has strong applicability.
