A data standardization processing method and device for medical big data

Abstract

The invention provides a method and device for data standardization processing of medical big data and relates to the technical field of medical entity identification. The method comprises the steps that a first group of candidate entities of a to-be-processed statement is determined according to an entity mark sequence of the to-be-processed statement; word extraction is conducted to the to-be-processed statement according to a preset medical noumenon term word extraction strategy, so a second group of candidate entities can be determined; entities in the to-be-processed statement are determined from the first group of candidate entities and the second group of candidate entities; screening is conducted according to preset syntactic analysis and screening rules, so a candidate standardization term in the to-be-be-processed statement can be determined; if the candidate standardization term in the to-be-processed statement can match a preset medical noumenon term library, the candidate standardization term in the to-be-processed statement can be determined as the standardization term; and if the matching fails, a matching failure problem report will be generated, or fuzzy matching will be conducted to the candidate standardization term which is not matched and belongs to a disease term type, so the standardization term can be determined.

Description

technical field [0001] The invention relates to the technical field of medical entity recognition, in particular to a data standardization processing method and device for medical big data. Background technique [0002] In recent years, with the development of medical and health informatization, the medical and health field has entered the era of big data. The medical business process is also a process of accumulating medical big data, which has a huge impact on the medical and health industry. For example, through the analysis and mining of medical big data, the comparative effect research of clinical operations, the construction of clinical decision support system, the research based on health economics and curative effect, and the analysis and research of disease patterns can be realized, so as to promote the development of medicine and improve the quality of clinical medicine. The current medical big data includes clinical data (such as electronic medical records, healt...
