ABNORMAL BEHAVIOR DETECTION DEVICE, METHOD, AND PROGRAM, AND DEVICE FOR CALCULATING RARE BEHAVIOR PARTIAL SERIES

摘要

PROBLEM TO BE SOLVED: To detect the abnormal action of an acting body whose series of preceding behaviors can affect subsequent behaviors and to specify the cause of the abnormal action. SOLUTION: A rare behavior partial series calculating part 142 receives a set 171 of behavior series including one or more behavior series 160 of the acting body and calculates a rare partial series (rare behavior partial series 172) appearing in the series. A behavior series retrieving part 143 extracts from the set 171 of behavior series a set 173 of behavior series including the rare behavior partial series 172. A behavior cause determining part 144 finds a common partial series 174 from the set 173 of behavior series including the rare behavior partial series, and regards behaviors in the common partial series 174 that appear before the rare behavior partial series 172 as the cause of the rare behavior partial series 172 to output it as a cause 175.
