Abstract

Aiming at the problems of difficult and low-accuracy named entity recognition in the motor field, this paper proposed a named entity recognition model in the motor field based on BERT and multi-window gated CNN. Firstly, the model used the BERT pre-training model to generate the character vector sequence of the sentence, and dynamically fine-tuned the character vector according to the context of the text in the motor field to enhance the semantic expression of the character vector; Secondly, it constructed a double-branch feature extraction layer with a global time sequential feature perception unit and a multi-window gated CNN unit to form a multi-level semantic feature representation of sentence; Finally, it used CRF to decode the character sequence to obtain the corresponding label of each character. The results of comparative experiments with multiple models on the small-scale self-built motor field data set show that the named entity recognition performance of the model is better than other models, with macro-F1 values reaching 90.16%, which verifies the effectiveness of entity recognition in motor field.
