INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
First Claim
1. An information processing device comprising:
- a parameter setting unit that sets a parameter to be used for calculating a given statistic based on event occurrence time information related to a time when a certain event occurred;
a period dividing unit that divides a calculation period for which the given statistic is calculated into a plurality of unit periods based on a base unit time set by the parameter setting unit;
a count unit that counts a number of occurrences of the certain event for each of the plurality of unit periods based on the event occurrence time information; and
a statistic calculation unit that calculates a statistic indicating a pattern of occurrences of the certain event by using a count result of the count unit.

7. An information processing method comprising the steps of:
-
setting a parameter to be used for calculating a given statistic based on event occurrence time information related to a time when a certain event occurred; dividing a calculation period for which the given statistic is calculated into a plurality of unit periods based on a base unit time set in the parameter setting step; counting a number of occurrences of the certain event for each of the plurality of unit periods based on the event occurrence time information; and calculating a statistic indicating a pattern of occurrences of the certain event by using a count result in the counting step.

8. A program causing a computer to implement functions comprising:
-
a parameter setting function that sets a parameter to be used for calculating a given statistic based on event occurrence time information related to a time when a certain event occurred; a period dividing function that divides a calculation period for which the given statistic is calculated into a plurality of unit periods based on a base unit time set by the parameter setting function; a count function that counts a number of occurrences of the certain event for each of the plurality of unit periods based on the event occurrence time information; and a statistic calculation function that calculates a statistic indicating a pattern of occurrences of the certain event by using a count result of the count function.
