Abstract
An information processing apparatus determines a threshold value of the number of times of use of a keyword on the basis of the number of times of use of the keyword in each unit period included in a cycle period. Next, the information processing apparatus identifies a period in which the numbers of times of use exceeds the threshold value in the cycle period as a candidate of a popularity period of the keyword. Next, the information processing apparatus excludes the identified period from the popularity period if a situation in which the numbers of times of use in the identified period exceed the threshold value is different from a situation based on a periodic popularity of the keyword. When the identified candidate period is not excluded from the popularity period, the information processing apparatus determines the identified period to be the popularity period.
