Outline
To solve the problem of poor recognition performance of current traditional Chinese medicine case naming entity recognition models，and to improve the efficiency and accuracy of the structuring of traditional Chinese medicine cases.
A BDM-CRF named entity recognition neural network model was constructed to integrate multi-dimensional information. The model integrated Bidirectional Long Short-Term Memory（BiLSTM），Gated-Dilated Convolutional Neural Networks（DGCNN）and Multi-Head Attention（MHA）models for multi-dimensional feature extraction. The feature extraction results were constrained by the Conditional Random Field（CRF）model. The effectiveness of the model was verified through comparative experiments，ablation experiments，pre-training model comparison experiments and neural network structure comparison experiments，validating and demonstrating the extraction performance of the model through case analysis.
The model proposed in this study achieved an average improvement of 2.30% in precision，4.73% in recall and 3.53% in F1 score compared to those of the control model. The case analysis results indicated that the model in this study can correctly identify most of the entity content in the text of traditional Chinese medicine medical cases.
The proposed model for the named entity recognition in traditional Chinese medicine（TCM）medical records，which integrates multi-dimensional information，can achieve better recognition results，effectively improve the accuracy and efficiency of TCM medical record structuring，and promote the intelligent processing of TCM medical records.
