Abstract

The embodiment of the invention provides a standard symptom extraction method and device, electronic equipment and a storage medium. The method comprises the steps of determining a medical record textof a to-be-extracted standard symptom; extracting medical record symptom region characteristics of the medical record text, and performing standard symptom extraction based on the medical record symptom region characteristics of the medical record text and the standard symptom characteristics of each standard symptom to obtain a standard symptom extraction result corresponding to the medical record text, wherein the standard symptom characteristics of each standard symptom are determined based on a knowledge graph. According to the standard symptom extraction method and device, the electronicequipment and the storage medium provided by the embodiment of the invention, the accuracy of standard symptom extraction is improved, and meanwhile, the spectrum departure rate of a standard symptomextraction result is also reduced.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a standard symptom extraction method, device, electronic equipment and storage medium. Background technique [0002] With the rapid development of deep learning technology, medical record structuring methods based on deep learning emerged as the times require. Among them, the symptom information contained in the medical record is important information for diagnosing the disease suffered by the patient. Therefore, by extracting structured standard symptom information from unstructured medical records, it can play a key role in downstream tasks such as auxiliary diagnosis and treatment and medical record quality control. [0003] At present, the standard symptom extraction methods for medical records mainly include two types: the extraction method based on Conditional Random Field (CRF), and the extraction method based on the Encoder-Decoder model. How...
