This study compared semantic representation learning + machine learning, BERT, and GPT-4 to estimate disease names from chief complaints and evaluate their accuracy. Semantic representation learning + machine learning showed high accuracy for chief complaints of at least 10 characters in the International Classification of Diseases 10th Revision (ICD-10) codes middle categories, slightly surpassing BERT. For GPT-4, the Retrieval Augmented Generation (RAG) method achieved the best performance, with a Top-5 accuracy of 84.5% when all chief complaints, including the evaluation data, were used. Additionally, the latest GPT-4o model further improved the Top-5 accuracy to 90.0%. These results suggest the potential of these methods as diagnostic support tools. Future work aims to enhance disease name estimation through more extensive evaluations by experienced physicians.

This paper describes a method for constructing a learned model for estimating disease names using semantic representation learning for medical terms and an interpretable disease-name estimation method based on the model. Experiments were conducted using old and new electronic medical records from Toyama University Hospital, where the data distribution of disease names differs significantly. The F1-score of the disease name estimation was improved by about 10 points compared with the conventional method using a general word semantic vector dictionary with a faster linear SVM. In terms of the interpretability of the estimation, it was confirmed that 70% of the disease names could provide higher-level concepts as the basis for disease name estimation. As a result of the experiments, we confirmed that both interpretability and accuracy for disease name estimation are possible to some extent.
