Patent ID: 6873983

Claim:
An information use frequency prediction program which causes a computer to function as: a temporal operation unit which sequentially performs temporal operations in a unit of predetermined times, the temporal operations being performed with respect to a relative relation between a first pattern of a first data including use frequency based on first time series information that represents a temporal change of the use frequency of the first time series information of the first data, and a second pattern of a second data including use frequency of second time series information that represents a temporal change of the use frequency of the second time sense information based on the second data; a correlation coefficient calculation unit which calculates a correlation coefficient between the first time series information and the second time series information for each unit of the predetermined times based on the relative relation between the first and second patterns; a pair specifying unit which specifies a pair of the first time series information and the second time series information, corresponding to the correlation coefficient having the highest value, of a plurality of correlation coefficients calculated by the correlation coefficient calculation unit; and a prediction unit which predicts additional data of the use frequency of the first time series information constituting the pair based on the second pattern corresponding to the pair, and wherein a time corresponding to each data contained in the first data is different from a time corresponding to the additional data.
