An Automatic Recognition Method for Emergency Response Elements
Current research on the identification of emergency response elements faces the challenge of automatically recognizing data on disaster factors,response process,affected objects and so on.This paper establishes a four-dimensional model of emergency response elements,which are classified into eight categories covering safeguard measures,response measures and other processes,and proposes a TDA-RoBERTa-wwm-BiLSTM-CRF model.By adopting a template-based data augmentation strategy and integrating a pre-trained model with BiLSTM-CRF,the proposed model automatically identifies multiple factors of emergency events.The comparative and ablation study shows that the proposed model performs effectively in the automatic recognition of emergency response elements.
