Problems solved by technology

However, due to the limited knowledge stored by doctors themselves, when doctors encounter difficult and miscellaneous diseases, they need to consult medical knowledge to make a diagnosis. Moreover, since different diseases may have similar symptoms, in order to ensure the correctness of diagnosis results, Doctors need to inquire as much knowledge as possible to make a diagnosis, and in this way, the time spent on the entire diagnosis process will be prolonged, which makes the doctor's work efficiency low

Embodiment Construction

[0028] The following is a further detailed description through specific embodiments:

[0029] like figure 1 The illustrated smart question answering system based on knowledge graph includes a database, a query subsystem and an output module. The database stores a medical knowledge graph. The medical knowledge graph includes disease data obtained from a third-party Lanzhou University medical database. Including the associated disease name, disease nickname, symptom information and complication information, the query subsystem is used to obtain the patient's symptom information;

[0030] After acquiring the symptom information of the patient, the query subsystem queries the disease data containing the symptom information from the database, and the output module outputs and displays the disease data;

[0031] The query subsystem includes a query statement generation module, a query module, an operation module and an inquiry module. The query statement generation module generates...

Abstract

The present invention relates to the technical field of disease question answering, and one of the objects is to provide a knowledge graph-based intelligent question answering system, comprising a database, a query subsystem and an output module, wherein the database stores disease data, and the disease data includes associated disease names and symptom information, After the query subsystem obtains the symptom information, it queries the disease data containing the symptom information from the database, and the output module outputs and displays the disease data; the query subsystem includes a query module, an operation module and an inquiry module, and the query module receives After the symptom information of the patient is obtained, all the disease data including the symptom information are queried from the database. When the result of the "∪" operation is not empty, the result obtained by the "∪" operation is output to the output module as the disease data obtained by the query, and a method based on the above system is also provided.

Description

technical field [0001] The invention relates to the technical field of disease question answering, in particular to a knowledge graph-based intelligent question answering system and a method thereof. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to health as the source of life, so that in the future, the health industry will have unprecedented challenges and more exciting development opportunities. Moreover, as people pay more attention to health, hospitals are beginning to be crowded. [0003] When a patient sees a doctor, the doctor first asks about the patient's symptoms, the patient will tell the doctor about his physical discomfort, and then the doctor will make a diagnosis based on the information provided by the patient. And because the knowledge stored by the doctor is limited, when the doctor encounters difficult and miscellaneous diseases, he needs to consult medical knowledge to be able to diag...
