摘要:

In recent years, with the continuous increase of electronic medical record data, people have begun to pay attention to medical named entity recognition. Medical named entity recognition can transform the free text in an electronic medical record from information to data, so it has high research value and application value. However, most of the current deep learning methods use character-level segmentation for semantic feature extraction, which leads to the loss of local dependencies between characters. In order to solve this problem, this paper proposes a multi-word segmentation method, which mainly uses 'jieba' to segment as many sentences as possible, and then uses the BILSTM model to train the words after segmentation. The purpose of this method is to enrich the semantic features that can be used in the model learning process, so as to further improve the entity recognition ability of the model. Experimental results show that this method can improve the performance of the model. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
