UNUSUALNESS EVALUATION DEVICE, UNUSUALNESS EVALUATION METHOD, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To evaluate how different an event data series obtained by a user's behavior is from a standard pattern showing a user's daily behavior.;SOLUTION: A data acquisition part 11 acquires the event data series by the user's behavior. A pattern storage part 21 stores a standard pattern series showing the user's daily behavior. A score calculation part 31 calculates a matching score corresponding to an optimal alignment where similarity between the event data series and the standard pattern series becomes largest on the basis of dynamic programming. An optimal alignment acquisition part 32 acquires the optimal alignment on the basis of the matching score calculated by the score calculation part 31. A behavior evaluation part 33 evaluates a difference between events included in the event data series and the standard pattern series in the optimal alignment.;COPYRIGHT: (C)2011,JPO&INPIT
