Problems solved by technology

[0004] 1. Establishing a terminology dictionary requires a lot of expert knowledge and manual annotation, which is time-consuming and labor-intensive, and is prone to conflicts
[0005] 2. The colloquial expressions of users are ever-changing, and keyword matching can only include a small part of them, which severely limits the coverage of normalization

Abstract

A method for normalizing colloquial symptoms includes: receiving a colloquial symptom input by a user; Mapping the colloquial symptom to a pre-stored set of standard symptoms, and obtaining a standardsymptom having the highest cosine similarity score with a word vector of the colloquial symptom in the standard symptom set, and setting the standard symptom having the highest score as a normalizedsymptom of the colloquial symptom. The colloquial symptoms entered by the user are mapped to the preserved standard symptom set, and the standard symptom with the highest cosine score of the word vector of the colloquial symptoms is directly regarded as the normalized symptom of the colloquial symptoms. The invention avoids that the information input by the user can not be processed through the intelligent terminal. At that same time, a large amount of manpower time is avoid to be consumed for manual label. Normalization of symptoms into standard forms will greatly facilitate the standardization of medical records, medical atlas-based reasoning, electronic information exchange, and other applications.

Description

technical field [0001] The invention relates to natural language processing technology, in particular to a method for normalizing colloquial symptoms. Background technique [0002] At present, natural language processing technology, as one of the most important fields of artificial intelligence, has already demonstrated great value in search, advertising, dialogue and other directions. In the medical field, massive medical records, textbooks, papers, questions and answers and other medical data urgently need the development of natural language processing technology. Semantic understanding technology is the key technology to realize artificial intelligence. It can understand various user expressions into standard representations that computers can process. Existing similar technologies are all used to solve problems in non-medical fields and cannot be directly transplanted to the medical industry. [0003] The current term normalization is mainly a dictionary-based keyword ...
