The invention discloses a man-machine interaction hospital guide method and system based on global attention intention recognition, and the method comprises the steps: obtaining the disease description of a patient, carrying out the natural language understanding, obtaining a standard medical term, updating a current dialogue state, inputting the current dialogue state into a preset dialogue strategy model, and obtaining a dialogue action, wherein the dialogue action comprises a system intention and a processing result, the system intention is negative, confirmation, inquiry, notification or interaction ending, and the processing result is a symptom, a disease or a department obtained by processing; and when the system intention is negative, confirmation and inquiry, selecting continued iterative execution; otherwise, executing notification or ending interaction. According to the invention, defects and problems existing in related technologies of a conventional intelligent hospital guide system can be solved, i.e., how to analyze related disease information of oral disease description of a patient and mine disease information except the disease description of the patient is solved,natural man-machine interaction is realized, and the effect of the intelligent hospital guide system in practical application is improved.
