    • A time factor feature generation system includes: a use status grasping portion that extracts transition data showing variations in degree of use of a site from log data; a variation data generating portion that generates, based on the transition data, variation data expressing the variations in degree of use of the site as a group Y of values showing the degree of use of the site; a time factor data recording portion in which a plurality of time factors and time factor values of each of the plurality of time factors are recorded; a time factor extracting portion that generates groups Di of time factor values, each of which corresponds to a time factor extracted from among the plurality of time factors; and a time factor feature generating portion 13 that calculates coefficients ai such that a square of an error b has a minimum value in an equation in which the groups Di and the group Y are used as an explaining variable and an explained variable, respectively, thereby to generate data showing a time factor feature of a use status of the site. By this configuration, the time factor feature generation system generates data quantitatively showing a time factor feature of a use status of a site.
    • 时间因素特征生成系统包括:使用状态抓取部,其从日志数据提取表示站点的使用程度的变化的过渡数据; 变化数据生成部,其基于所述过渡数据生成表示所述场所的使用程度的变化的变化数据,作为表示所述场所的使用程度的值的组Y; 时间因素数据记录部分,其中记录了多个时间因素中的每一个的多个时间因素和时间因子值; 时间因子提取部分,其生成时间因子值的组D i,其中每个时间因子值对应于从多个时间因子中提取的时间因子; 以及时间因子特征生成部分13,其计算系数α1,使得误差b的平方在组D和i中的等式中具有最小值, 组Y分别用作解释变量和解释变量,从而生成表示站点使用状态的时间因子特征的数据。 通过该配置,时间因子特征生成系统生成定量地显示站点的使用状态的时间因素特征的数据。
