Outline of Final Research Achievements

This research investigated process-dynamics mining, which facilitates knowledge discovery from spatiotemporal process sequences. Followings are main contributions. (1) Proposed a method to visualize the dynamics of outpatients in a hospital based on the clinical action records and input device locations. (2) Proposed a method to analyze the relationships between the stay time of outpatients and treatment processes they received during their hospital visits. The results suggested that a visit needs long time if treatments or examinations should be executed during the consultation, or if injections such as intravenous drips were involved in the process. (3) Proposed a temporal pattern mining method based on ranged relations. Experimental results demonstrated that the proposed method could generate frequent patterns with abstracted time ranges embedded in their temporal relations.
