Named Entity Recognition (NER) is a long-standing fundamental problem in various research fields of Natural Language Processing (NLP) and has been practiced in many application scenarios. However, the application results of NER methods in Chinese electronic medical records (EMRs) are not satisfactory...
In order to overcome the problems of unstructured, multiple meanings of words and unclear word boundaries in text of Chinese electronic medical records, this paper proposes a medical entity recognition method based on RoFormerV2-BiLSTM-CRF fusion model, using BIO annotation method to annotate the ...
