This research builds a social media public opinion early warning index system based on crisis informatics, and takes the epidemic report in the mainstream news Weibo media People's Network as an example, aiming to explore the role of social media in major public health emergencies. The study found that social media has played an important role in crisis response. The measurement results of People's Daily Online show that although the early warning index of social media is green and safe, that is, it is safer, there are still problems such as untimely and inaccurate crisis early warning, and lack of attention to crisis recovery.
