Abstract:

Air traffic control (ATC) special situation is a special emergency situation encountered in the process of civil aviation transportation, and the principle of ATC disposal is as accurate and efficient as possible. If it is not disposed effectively, it will lead to major flight accidents. However, the traditional special situation disposal relies on manual labor, which is difficult to meet the requirements of precision and efficiency. Knowledge graph technology is used to extract, represent and manage ATC special situation information, and to assist ATC personnel in special situation disposal, which can effectively improve the emergency disposal efficiency of ATC special situation. Therefore, a top-down knowledge graph construction method for ATC special situation disposal is proposed. Firstly, the concept, relationship and knowledge structure of knowledge graph are defined from top to bottom to form a pattern layer. Then, considering the small amount of training in ATC special situation case records and the large number of domain entities, the entity extraction model which combined bi-directional long short-term memory (BiLSTM) network deep learning model and rule knowledge entity extraction model of bi-directional encoder representations from transformers (BERT)-BiLSTM-conditional radom fields (CRF)+regular expression (RE) is adopted to extract entities. On this basis, the BiLSTM+self-attention (SA) model is used to extract the relationships among entities. After that, the Jaccard correlation coefficient is used for knowledge fusion. Finally, the knowledge graph of the constructed ATC special situation disposal is visualized by using Neo4j graph database, and its application prospect in decision support of ATC special situation disposal in civil aviation is analyzed, providing references for the practical application of ATC department.
