Embodiment Construction

[0061] The present invention will be further explained below by taking the process of establishing a mapping relationship between the drug dictionaries A and B of two domestic hospitals as a specific example.

[0062] (1) Select sample terms, divide each sample term into several fields, and encode the vocabulary of each field separately, the fields in each sample term include a main field, and the rest are attribute fields;

[0063] Starting from the criteria of source authority, terminology integrity, and clinical practicability, the drug public query database of the State Food and Drug Administration is selected here as a sample term for drug terms. Combining with the "Chinese Drug Generic Name Naming Principles" formulated by the National Pharmacopoeia Commission, drug terms are divided into 4 fields: applicable population, active ingredients, route / usage and dosage form. Vocabulary is collected and coded from sample terms according to the divided fields. Since the field o...

Abstract

The invention discloses a method and a system for automatically establishing a medical term mapping relationship based on word segmentation and coding. The method comprises establishing the mapping relationship between terms of a dictionary A and terms of a dictionary B, and specifically comprising the steps of 1, dividing each sample term into a main field and an attribute field; 2, establishing a main field table by the main fields and codes obtained in the step 1, and establishing a word segmentation dictionary by common Chinese characters and the attribute fields; 3, performing Chinese word segmentation on words in the main field table; 4, performing Chinese word segmentation on the terms of the dictionary A; 5, computing correlation degree between the main field of each sample term and the main field of the corresponding term of the dictionary A; 6, matching and coding the main fields of the sample terms and the main fields of the terms of the dictionary A according to the correlation degrees; and 7, coding the main fields of the terms of the dictionary B, and establishing the mapping relationships aiming at the terms, with the same main field codes, of the dictionary A and the dictionary B. According to the method, the problem that the manual term mapping efficiency is low thus medical information is difficult to be shared is solved.

Description

technical field [0001] The invention relates to a medical system data processing method, in particular to a medical term conversion or mapping method and a mapping system between different standards. Background technique [0002] Medical terms are professional terms in the medical field, used to refer to various things, phenomena, characteristics, relationships and processes in the medical field (such as diseases, drugs, surgical operations, inspections, etc.). These terms are necessary components of clinical information systems to express medical information. [0003] Internationally, with the joint efforts of many standardization institutions and organizations such as the World Health Organization (World Health Organization, WHO), the National Library of Medicine (The National Library of Medicine, NLM), and the International Health Terminology Standards Development Organization (IHTSDO), a new standard has been formed. A series of medical terminology standards and termino...
