A privacy-aware healthcare question answering system using knowledge graphs & large language models

What is it about?

Medicient is a system that can answer health questions and protect patient privacy. Medicient uses a knowledge graph, which is a way of organizing information from different sources, such as patient records, drug databases, and medical research. Medicient can use this information to give personalized recommendations for treatment or medication based on the patient’s condition and history. Medicient also hides the patient’s data from large language models, which are powerful tools for understanding and generating natural language, but can also pose privacy risks. Medicient aims to help doctors and patients make better decisions in healthcare while keeping their data safe.

Why is it important?

We introduce a new system that can help users find the best treatment or medication for their health problems. The system uses a knowledge graph, which is a way of connecting different kinds of information from patient records, drug databases, and medical research. The system can answer health questions and give personalized recommendations based on the patient's condition and history. The system also protects the patient's privacy by hiding their information from large language models, which are powerful but risky tools for understanding and generating natural language. We show that this system is better than using large language models alone, which may not have the right information or may reveal sensitive data.
