Abstract:

To achieve efficient and accurate risk identification of massive notice to airmen text data, meet the needs of modern flight operations for notice to airmen risk analysis, and enhance risk identification capabilities in the civil aviation field, a notice to airmen risk identification model integrating the pre-trained ERNIE, CNN, and BiLSTM model is proposed. The ERNIE model is used for word vector training, CNN is utilized to capture the characteristics of the local structure of the text, and the BiLSTM is combined to understand the in-depth contextual associations of the text; comparative experiments are conducted for verification. The results show that compared with other similar models, the recognition accuracy of this method for domestic Chinese and international English notice to airmens is as high as 92.01% and 93.85% respectively. This achievement can provide certain data support for airlines in risk analysis of flight intelligence and safety management.

Key words: natural language processing (NLP), notice to airmen, risk identification, enhanced representation through knowledge integration (ERNIE), convolutional neural networks (CNN), bidirectional long short-term memory (BiLSTM)
