APPARATUS AND METHOD FOR GRAPH MODEL BASED ACTIVITY PATTERN MINING FOR HEALTHCARE

摘要

PURPOSE: A device for mining an activity pattern based on a graph model for health care and a method thereof are provided to generate an activity graph with various window times, thereby expressing the time sequence between various information activity patterns and an activity. CONSTITUTION: An activity graph generation unit(110) generates an activity graph which combines day activity sequences included in a window. An activity pattern mining unit(120) mines a useful activity pattern from the activity graph. The activity graph generation unit includes a sequence combination unit(112), which generates the activity graph, by combining the daily activity sequences with a day activity sequence generation unit(111) which generates the day activity sequences composed of the connection among activity nodes. The sequence combination unit finds the same activity sequence segments included in the window and combines the same as a single sequence.
