The invention discloses a
disease type prediction method and
system based on a medical bill and a pseudo-
label mechanism, and the method comprises the steps: obtaining a medical bill set which comprises a
medicine list, a doctor-seeing department and patient portrait information, and carrying out the
standardization preprocessing, and generating standardized bill data; respectively inputting the standardized bill data into a dynamic reasoning
knowledge base and a pre-trained large
language model, generating a first pseudo-
label disease set through a rule reasoning engine, and generating a second pseudo-
label disease set through the guidance of a semantic understanding cue word template; and fusing the two pseudo-label
disease category sets to obtain a fused pseudo-label, training a multi-label
disease category classification model by taking the fused pseudo-label as a target, and finally realizing
disease category prediction of the to-be-predicted medical bill data. According to the invention, through a dual pseudo-tag generation mechanism fusing rule reasoning and a large
language model, the problem that the medical bill data lacks a real disease category tag is solved, the accuracy and reliability of disease category prediction are improved, and a reliable solution is provided for deep utilization of the medical bill data.
