Research on Emergency Dynamic Classification and Grading Based on Network Public Opinion Heat

Network public opinion heat is an important factor in the emergencies response process. According to public opinion of the monitoring platform, we construct the method of dynamic classification and grading based on network public opinion heat, and analyze the specific factors such as heat score, turning point, duration time, and public opinion content. The research shows that the adjusted emergency dynamic classification and grading can match with the actual progress of emergencies, which provides reference to the emergencies real-time response.
