An information processing device including: an input unit that receives time-series data including a plurality of data input in time series and having a correlation in at least a part between the data; and a division unit that temporally divides the time-series data by a first divider width to cause an analysis system to perform a first analysis process of the time-series data with the first divider width and temporally divides the time-series data by a second divider width that is longer than the first divider width to cause the analysis system to perform a second analysis process of the time-series data with the second divider width.
