The invention relates to the field of
data processing, in particular to an intelligent extraction method and
system for reference information of a patient in a
recovery period, and the method comprises the steps: recognizing the motion condition and
motion intensity of a user through motion data collected by an intelligent wearable device, and accumulating the current motion duration of the patient when the
motion intensity reaches a certain value; meanwhile, collecting physical sign data of the user in real time, determining reference physical sign data matched with the patient from a physical sign
reference database in combination with the current
exercise intensity, and calculating the similarity between the actually measured physical sign data and the reference physical sign data. If the similarity is too low, it can be deduced that the patient possibly feels uncomfortable during movement, at the moment, a
question answering process is executed through a pre-constructed question template, and a symptom entity possibly appearing during movement of the patient is found. Finally, the accumulated
exercise duration, the symptom entity, the actually-measured sign data and the
exercise intensity data serve as key data to be extracted and provided for doctors, and the doctors have related data to refer to and judge the
recovery condition of the patient.
