NAMED-ENTITY RECOGNITION METHOD AND APPARATUS, COMPUTER DEVICE AND READABLE STORAGE MEDIUM

摘要

A named-entity recognition method and apparatus, a computer device and a readable storage medium. Said method comprises: acquiring a medical text, and preprocessing the medical text, so as to obtain a text to be processed (S100); on the basis of a preset dictionary, performing microbial entity extraction on the text to be processed, so as to obtain a target entity (S200); generating a plurality of candidate abbreviation entities according to a first preset rule and the target entity, and performing screening, by using a first model, from the candidate abbreviation entities, so as to obtain the candidate abbreviation entity corresponding to the entity and take same as a target abbreviation entity (S300); generating a plurality of candidate supplementary entities according to a second preset rule and the target entity, and screening the candidate supplementary entities by using a second model, so as to obtain a target supplementary entity (S400); and generating target data on the basis of the target entity, the target abbreviation entity and the target supplementary entity (S500). The present invention solves the technical problem of relatively low accuracy caused by a dictionary matching-based entity extraction method being unable to take entities having abbreviations or specific information into consideration.
