| Outline of Final Research Achievements |
We focused on systematic clinical records (clinical paths) of clinical practice and patient condition, aiming at discovering problem factors and applied machine learning and visualization. For example, machine learning was applied by taking records of long-term inpatients as positive cases and other records as negative cases, and feature words and examination values indicating important factors were extracted, and the discrimination performance was evaluated. In the visualization, we realized an interactive factor time series evolution graph that facilitates interpretation and a system that supports creation of template of medical record.
