Abstract

The embodiment of the invention belongs to the technical field of artificial intelligence, and relates to a named entity identification method. The method comprises the steps: receiving an identification request carrying an original text sent by a user terminal; carrying out preprocessing operation on the original text to obtain annotation data; inputting the annotation data into a trained entityprediction model to perform entity prediction operation, and obtaining an entity prediction result; taking the entity prediction result meeting a prediction threshold as an entity identification result; and outputting the entity identification result to the user terminal. The invention further provides a named entity recognition device, computer equipment and a storage medium. The generalization ability of the model is improved; disease entities which do not appear in the dictionary base can also be identified and processed; a new disease combination entity can also be identified; the model can identify the disease entity according to the context semantic information, and the recall rate and accuracy of the model are improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a named entity recognition method, device, computer equipment and storage medium. Background technique [0002] Named Entity Recognition (NER) in electronic medical records is to find out some clinical entities related to patients from the descriptive text of electronic medical records, such as the patient's diseased part, symptoms, used drugs and operations, etc. . Named entity recognition of Chinese electronic medical records is the key to information extraction of Chinese electronic medical records, which can lay the foundation for Chinese health information processing such as medical record retrieval, disease prediction, and construction of medical knowledge graphs. However, there are many unregistered words in electronic medical records, and the number continues to increase. Moreover, compared with English, the recognition task of Chinese named...
