Abstract (in Japanese) (See Japanese page) 
(in English) In the medical practice, vast medical data are accumulated every day with medical computerization now. Due to increasing those data, the importance of utilizing them also increases. In particular, the analysis of the non-structured text data such as medical records has been developing, and it is demanded analyzing using them effectively. In this study, we predicted the long-term hospitalization patient from the medical records, from the inpatient who received proximal thighbone bone fracture operation to a discharge, with two machine learning methods, SVM and Decision Tree. In addition, we analyzed the factor that showed a difference of the predicted performance of two method.
