摘要：After the occurrence of major safety accidents, the key to prevent similar accidents from happening again is whether all sectors of society can get deep reflection from the investigation and accountability of accidents, and then improve the level of safety awareness and safety management and control through the process of learning from incident (LFI). Taking "Tianjin Port 8.12 major dangerous chemical explosion accident" as an example, 610 articles related to the accident were exported from CNKI as samples. The topic classification of the abstract text was carried out by using LDA topic model. Finally, based on the theory of learning from incident (LFI), the evolution trend and content of the topic of reflection were analyzed. The results show that: (1) the content of reflection mainly includes the following four topics: (I) Risk of hazardous chemicals and safety of enterprises; (II) Emergency management and rescue; (III) Government public crisis management; (IV) Public opinion crisis in emergencies (2) the proportion of research on topic II is lower than that of other topics, and there may be insufficient reflection on individual issues. As it has the function of reducing accident harm, it is of great significance and should be given enough attention.
