作者:

Highlights:

• A Multi-head Self-attention-based BiLSTM-CRF model (MUSA-BiLSTM-CRF) for Chinese clinical named entity recognition

• An improved character-level feature representation method combining character embedding and character-label embedding

• Performance evaluation of models on the CCKS 2017 Task 2 benchmark dataset and the CCKS 2018 Task 1 benchmark dataset.
