Embodiment Construction

[0048] like figure 1 As shown, the human-computer interaction guidance method based on global attention intent recognition in this embodiment includes:

[0049] S1) Obtain the condition description in the patient's current dialogue;

[0050] S2) Obtain standard medical terminology through natural language understanding for disease descriptions;

[0051] S3) Update the current dialogue state with standard medical terminology S t , the current dialog state S t Input the preset dialogue policy model to obtain dialogue actions a t , the dialogue policy model is trained to establish the current dialogue state, dialogue action a t The mapping relationship between dialogue actions a t Contains the system intent and processing result, the system intent is to deny, confirm, inquire, inform or end the interaction; the processing result is the obtained symptoms, diseases or departments;

[0052] S4) If the dialogue action a t If the system intent is negative, confirm, or quer...

Abstract

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.

Description

technical field [0001] The invention relates to a natural language understanding and dialogue system, in particular to a human-computer interaction guidance method and system based on global attention intention recognition. Background technique [0002] The complexity and inefficiency of traditional manual medical guidance has always been the pain point of most hospitals, and only relying on the auxiliary guidance of medical staff lacks certain efficiency. At the same time, in recent years, people's attention to health has increased significantly, the frequency of hospital flow peaks has become higher and higher, and the human resources for medical guidance are obviously insufficient. With the development of medical informatization, medical guidance robots have gradually come into people's field of vision. The use of robots for intelligent medical guidance can effectively divert hospital patients reasonably, and at the same time allow patients to enjoy a new experience of in...
