In December 2021, four Neo4j engineers, together with Maruthi and I, developed a medical chatbot called Doctor.ai in the Singapore Healthcare AI Datathon & EXPO 2021. Doctor.ai manages electronic health records in a Neo4j graph and interacts with its users in English thanks to AWS Lex.
After the Datathon, we have continued to expand Doctor.ai. After the integration of three public knowledge graphs, Doctor.ai knows about diseases, genes, pharmaceutical compounds, symptoms and so on. This expansion connects patients’ health records to the medical knowledge network. In other words, it connects the specific to the general. Now we can understand each patient’s medical history in a much broader context. For example, after we ask for a patient’s last diagnosis, we can ask further what caused the disease and which drugs can be used.
