Abstract:Electronic medical records(EMR) are a product of the rapid development of medical information and are currently stored in the form of unstructured text. By using natural language processing(NLP) techniques to extract a large number of medical entities in unstructured text, it will help to improve the efficiency of medical personnel in accessing medical records, while the results of identification will also assist in the next research such as relationship extraction and knowledge graph construction. This paper introduces several commonly used datasets, corpus annotation criteria and evaluation metrics. This paper elaborates on the named entity recognition methods of electronic medical records from four aspects:early traditional methods, deep learning methods, pre-trained model, and small sample problem processing, and compares and analyzes the advantages and limitations of each model itself. The shortcomings of the current research are discussed, and the future development direction is proposed.
Keywords:electronic medical records(EMR)   natural language processing(NLP)   named entity identification   deep learning
