Chinese Clinical Named Entity Recognition with ALBERT and MHA Mechanism
Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022 Traditional clinical named entity recognition methods fail to balance the effectiveness of feature extraction of unstructured text and the complexity of neural network models. We propose a model based on ALBERT and a multihead attention (MHA) mechanism to solve this problem.

Chinese Medical Entity Recognition Model Based on Character and Word Vector Fusion
Scientific Programming, Volume 2021, Issue 1, 2021., 2021 The medical information carried in electronic medical records has high clinical research value, and medical named entity recognition is the key to extracting valuable information from large‐scale medical texts. At present, most of the studies on Chinese medical named entity recognition are based on character vector model or word vector model.
