| Abstract(in English) | The goal of our research is to achieve high classification accuracy for DPC(Diagnosis Procedure Combination)coding from diagnosis and treatment information using machine learning techniques. We use the approach of combining various classifiers, such as naive Bayes classifier and a classifier using a concept-base(a set of concept vectors for words). Therefore, we derive the concept-base specialized in medical field from discharge summaries and examine the capability of it through experiments of DPC coding. Discharge summaries are also used for inputs of classifiers. Experimental results of DPC coding using this concept-base show its usefulness and effectiveness of our approach. Our method of DPC coding achieves 76.0 percent accuracy in all 14 digits and 88.5 percent accuracy in first 6 digits. |
