Abstract:
1. An information management device comprising: a data storage unit that stores a plurality of data; a utilization unit that utilizes the data; a period specifying unit that specifies a period in which the data are utilized by the utilization unit; a correlation giving unit that correlates one data and another data with each other when one period specified by the period specifying unit for the one data stored in the data storage unit and another period specified by the period specifying unit for the another data stored in the data storage unit overlap each other; a search unit that searches out the another data correlated with the one data by the correlation giving unit by using one identification information piece to identify the one data as a first search condition; an output unit that outputs another identification information piece to identify the another data extracted by the search unit as being correlated with the one data; a detection unit to detect that the another data is utilized by the utilization unit or that the another data is replaced with the one data and then another data is searched out by the search unit, on the basis of the another identification information output by the output unit; a score giving unit that gives a score to the correlation of the another data output by the output unit with the one data correlated with the another data on condition that it is detected by the detection unit that another data is utilized by the utilization unit or is searched out by the search unit; an accumulation unit that accumulates the score given by the score giving unit; a score storage unit that stores the score accumulated by the accumulation unit; and an output control unit that controls to output the another data, to the correlation of which with the one data the score is given, in the order of the score stored in the score storage unit, wherein the period specifying unit is configured to: specify the one period in which the one data is utilized based on a utilization start time of the one data and a utilization end time of the one data; specify the another period in which the another data is utilized based on a utilization start time of the another data and a utilization end time of the another data, and wherein the utilization start time and the utilization end time indicate at least one of year, date and time of day.
