Claim:
A time species characteristic generation system being constructed on a computer that includes at least one processor, comprising: a use status grasping portion that extracts, from log data showing a use status of at least one site that is provided by a computer connected to a network, transition data showing variations in degree of use of the site in a predetermined time period; a variation data generating portion that generates, based on the transition data, variation data expressing the variations in degree of use of the site in the predetermined time period as a group Y of values showing the degree of use of the site; a time species data recording portion in which data showing a plurality of time species and a time species factor value representing a time period specified by each of the plurality of time species are recorded; a time species factor extracting portion that extracts a time species in accordance with a prerecorded procedure from among the plurality of time species recorded in the time species data recording portion and generates i groups D i of time species factor values, each of which represents a period that is specified by each of the extracted time species and is in the predetermined time period; and a time species characteristic generating portion that calculates, using the processor, i coefficients a i such that a square of an error b has a minimum value in an equation below (Mathematical Equation 1) in which the group Y showing the degree of use of the site in the predetermined time period are expressed by the groups D i of time species factor values and generates data including the coefficients a i and the time species corresponding to the groups D i , as data showing a time species characteristic of a use status of the site Y = ∑ i ⁢ ⁢ a i ⁢ D i + b .
