Problems solved by technology

[0004] Therefore, it is difficult to guarantee the accuracy of labeling medical texts by using the general text labeling method. Not only will it not save the workload of manual labeling, but the resulting wrong labeling results will also lead to the need for manual intervention to correct the labeling results, thereby reducing the labeling of medical texts. efficiency

Abstract

The present invention provides a medical text entity labeling method and device. The method includes: obtaining a set of marked medical texts; in the set of marked medical texts, determining the middle part expression corresponding to each marked entity , and determine the front part expression and the back part expression corresponding to each marked entity; determine the regular expression-based entity labeling template corresponding to each marked entity; Medical texts other than medical texts are annotated with entities. The medical text entity labeling method provided by the embodiment of the present invention extracts entity labeling templates from pre-labeled medical texts through a semi-supervised labeling method, realizes automatic labeling of large batches of medical texts, and simultaneously takes into account when extracting entity labeling templates The text characteristics of the entity itself and its context improve the accuracy of medical text entity annotation and reduce the workload of manual intervention.

Description

Technical field [0001] The present invention relates to the field of medical large data, and more particularly to a medical text entity labeling method and apparatus. Background technique [0002] With the wide application of intelligent medical technology, the demand for medical text such as electronic cases is gradually improved using natural language processing technology. However, the lack of medical labeling text language libraries for artificial intelligence model training is still a bottleneck that restricts intelligent medical technology applications. The current still requires users to marke a large number of medical texts according to actual scenes and needs. Medical text entity labeling is one of the important techniques of various entities in medical text, and is one of the important technical components of intelligent medical care. The technology hits a specific metadata tag for text content by clearing the text content to create a large amount of entity labeling med...
