| [Objective/Significance] In order to mine the risk information and event evolution law contained in aviation safety information and carry out visual display of knowledge, improve the acquisition efficiency of safety risk related content in aviation safety information and realize data-driven safety risk management. [Methods/Processes] Semantic triples are extracted from the information content through dependency parsing analysis and semantic role labeling. Based on LDA topic model and topic strength, risk topic modeling and core risk topic determination are carried out for the semantic information, and aviation safety information knowledge model is constructed to form a risk topic semantic map. [Results/Conclusions] Through the example verification, this study identifies the determined core risk information and constructs the semantic map of aviation safety information based on subject division, which provides an effective solution for the in-depth analysis and application of aviation safety information. |
