Chinese electronic case medical entity word class labeling method

Abstract

The invention discloses a Chinese electronic medical record medical entity word class labeling method, which comprises two parts: the first part is fine-grained Chinese electronic medical record medical entity class division rule making and corpus data set construction; the second part is a Chinese electronic medical record medical entity word class labeling method based on a combined gating attention mechanism; a fine-grained Chinese electronic medical record medical entity labeling rule is formulated according to Chinese electronic medical record text characteristics, a Chinese electronic medical record medical entity corpus data set is constructed according to the rule, and a GATTLCN model combined with a gated attention mechanism is invented based on Chinese electronic medical record text characteristics. Context elements needing to be focused are dynamically selected through the gating attention network to enhance text focusing, and the model effect is improved. By applying the method, the defects in the aspect of Chinese electronic medical record fine-grained medical entity word class labeling are overcome.

Description

technical field [0001] The present invention relates to the field of medical entity part-of-speech labeling, specifically including the construction of Chinese electronic medical record medical entity category labeling rules and data sets, and a Bi-LSTM+CRF joint network model (GATTLCN model) combined with a gated attention mechanism for Chinese electronic medical records. A method for medical entity part-of-speech tagging in medical records. Background technique [0002] In the context of the rapid development of science and technology, with the continuous development of "Internet + medical" technology, more and more research has begun to focus on the intersection of computer and medical information. In the era of rapid development of medical informatization, major hospitals have accumulated a large amount of clinical electronic medical record data. Electronic Medical Record (EMR) is also called computer-based patient record. It uses electronic equipment (computers, elect...

Problems solved by technology

However, in the special field of medical entity part-of-speech tagging in Chinese electronic medical records, due to the lack of a unified medical entity classification standard and the unique grammatical structure and text style of electronic medical records, the existing annotation toolkits cannot be used in Chinese electronic medical records.
