Abstract:The beginning of medical data mining is CNER(named entity recognition of Chinese electronic medical record).The target of medical data mining is to recognize unstructured text from related entities(anatomical parts,drugs,image examina-tion,etc.).Based on the need of improving the accuracy of CNER,This paper designs the BERT-BiLSTM-CRF model fusion do-main dictionary technology,which can fully combine the context semantic relationship,solve the polysemy problem,and obtain the long-distance dependence of EMR sentences.When CNER uses the BERT-BiLSTM-CRF model to fuse the domain dictionary tech-nology,the value of F1 has been confirmed by the experimental results,which is of great significance to the construction knowledge graph,clinical decision support system and medical record quality control system.
