Abstract
Online medical diagnosis refers to diagnosing diseases and providing treatment suggestions on the websites. It develops rapidly and has become a new choice for patients to seek medical treatment. Although manual online medical diagnosis is reliable, it has problems such as low efficiency, heavy burden on doctors, and long waiting time for patients. Relying on machines for automatic disease diagnosis is highly efficient, which, however, has low accuracy and reliability. In general, online medical diagnosis usually has two stages: inquiry and diagnosis. Inquiry stage refers to asking about the patient’s physiological, where the questions are usually streamlined, and thus can be handled by the machine. Diagnosis stage is to diagnose the disease and provide medical recommendations, which has strict requirements for accuracy and safety, and thus should be handled by the human. Inspired by this, in the paper we propose a human-machine collaboration based online medical diagnosis system, i.e., HM-MDS. In inquiry stage, the system employs the machine. It uses the BERT+CRF to identify symptoms in the patient’s dialogue and uses a DQN-based method to ask about symptoms. In diagnosis stage, the system employs both the machine and the human. The machine generates a pre-diagnosis result by calculating disease probability. Then the human doctor gives the final diagnosis result by checking the pre-diagnosis result and revising it if necessary. Obviously, HM-MDS can effectively save human doctor’s time as well as patient’s time, while ensure the accuracy of the diagnosis result. We conduct experiments on a real-world dataset. The results show our approach improves the online medical diagnosis’s reliability as well as patient satisfaction, and ensures diagnosis accuracy. The time cost for a reliable medical diagnosis is reduced to 36% compared with pure manual work.
