Doctor.ai, a Voice Chatbot for Healthcare, Powered by Neo4j and AWS

Doctor.ai is a voice virtual assistant powered by graph database Neo4j and AWS, designed to provide healthcare-related functionalities. It uses natural language understanding engine Lex and Lambda function to query the Neo4j database, mapping large amounts of medical records to a graph and recommending treatments based on similarity with other patients' lab results. The system has potential for improvement, including enhancing voice interaction, expanding treatment recommendation capabilities using knowledge graphs like Hetionet, and exploring open-source alternatives due to AWS reliance. Despite its limitations, Doctor.ai demonstrates that functional medical chatbots are within reach, offering a possible bottom-up adoption pathway for individual patients or doctors.
