Hypertensive patient intelligent question-answering system based on knowledge graph and establishment method thereof

Abstract

The invention relates to a hypertensive patient self-comprehensive management intelligent question-answering system based on a knowledge graph and an establishment method thereof. The system comprisesa user system interaction layer, a voice text conversion layer, a matching reasoning layer, an information search layer and a resource layer, wherein the resource layer is used for realizing data acquisition, knowledge extraction, knowledge fusion and processing and knowledge updating to form a framework of the knowledge graph; the user system interaction layer is used for carrying out language interaction with a user and answering questions raised by the user; the voice text conversion layer is used for completing conversion between voice and text; the knowledge graph can analyze the questions presented by the natural language of the user, understand the questions of the user and complete knowledge reasoning; the information search layer is used for searching or completing reasoning in the resource layer based on the text converted by the voice text conversion layer; and the matching reasoning layer is used for matching the information searched by the information search layer with the questions raised by the user, outputting matched answers after matching succeeds, and outputting specific answers if matching fails.

Description

technical field

[0001] The invention relates to the field of medical and health technologies, in particular to an intelligent question-and-answer system for self-comprehensive management of hypertensive patients based on a knowledge graph and a method for establishing the same. Background technique

[0002] In China, the prevalence of hypertension among residents aged 18 and over is 25.2%, the treatment rate is 41.1%, and the control rate is 13.8%. A low control rate greatly increases the risk of developing hypertensive complications. Foreign clinical trials have shown that good blood pressure control can reduce the risk of stroke by 30%-43%, and reduce the risk of myocardial infarction by 15%, which can save a lot of social medical resources and greatly reduce the pressure on patients.

[0003] Active community intervention and self-management are effective ways to control hypertension. Among them, grass-roots medical and health institutions (community health service cent...
