Zusammenfassung:	The invention discloses a civil aviation control operation safety risk perception method based on a topic model, and the method comprises the steps: carrying out the risk topic keyword extraction of a control operation unsafe event report through employing an LDA topic model, building a BERT model in the civil aviation control field, and constructing a civil aviation control operation safety risk semantic network. According to the method, professional cognition on a control unsafe event report is enhanced, correlation evolution generality of all risk themes is quantified, a complex unstructured safety management process data analysis mechanism based on natural language processing is formed, and the civil aviation control operation safety risk perception level is enhanced. According to the civil aviation control operation safety risk perception method based on the topic model, the obtained civil aviation control operation safety risk semantic network can quantify the correlation degree between keywords and rev
