Abstract
In order to effectively prevent the occurrence of aircraft runway accidents, the improved text topic model (LDA) and association algorithm (Apriori) were used to dig out the causes of aircraft runway safety accidents and analyze the correlation between them. Firstly, 181 accident investigation reports were obtained after collecting nearly 20 years of aircraft runway accident investigation reports. Secondly, the collected text data was cleaned and the text was processed by the TF-IDF algorithm in the improved LDA model, and the ten topics of the accident text, the key feature words representing each topic and the probability distribution in the text were obtained. Finally, the association rules of each topic and subject term are analyzed, and the strong association rules are excavated to understand the key causal factors of aircraft runway accidents.
