First-aid knowledge question-answering method based on multi-modal knowledge graph and system thereof

Abstract

The invention relates to a first-aid knowledge question-answering method based on a multi-modal knowledge graph and a system thereof, and the method comprises the steps: obtaining first-aid related knowledge based on the Internet, and constructing the multi-modal first-aid knowledge graph according to the first-aid related knowledge; acquiring a question input by a user, and extracting entities and relationships in the question by using the entity and relationship joint extraction model; positioning entities in the multi-modal first-aid knowledge graph according to the entities in the question, and determining matched entities; calculating the similarity of all relationships between the entities in the question and the matched entities by using a deep learning model; determining answers to the questions according to the similarity; and inputting the answer into the machine translation model according to the target language selected by the user, and outputting the translated answer. According to the first-aid knowledge question-answering method based on the multi-modal knowledge graph and the system thereof, first-aid knowledge learning can be carried out online, the learning convenience and the first-aid effect of social citizens are improved, multi-language translation can be carried out, and the first-aid efficiency is improved.

Description

technical field [0001] The invention relates to the field of first aid knowledge question answering, in particular to a first aid knowledge question answering method and system based on a multimodal knowledge map. Background technique [0002] Out-of-hospital first aid is a basic link in the "three-ring theory" of the trauma treatment system (out-of-hospital emergency medical care, in-hospital first aid, and critical ICU). However, at present, out-of-hospital first aid is a relatively weak link in China's medical care. Taking out-of-hospital cardiac arrest as an example, statistics show that 500,000 people in China die each year due to cardiac arrest, and less than 3% of them can be saved. When a patient suffers from cardiac arrest, 90% of the patients can be saved if they get effective CPR within 1 minute; 50% of the patients can be saved if they get effective CPR within 4 minutes; only 10% of the patients can be saved if they get effective CPR within 6 minutes. It takes ...
