1. An information processing apparatus comprising: an interpolation unit configured to interpolate, by using an interpolation model, at least either of first feature amounts extracted from a plurality of medical images contained in case data and second feature amounts extracted from a plurality of medical images contained in inspection data; a calculation unit configured to calculate similarities between the plurality of medical images contained in the inspection data and the plurality of medical images contained in the case data by comparing the first feature amounts with the second feature amounts on a display unit; an output unit configured to output case data selected based on the calculated similarities; and a display control unit configured to display an interpolated feature amount, the first feature amounts, and the second feature amounts, wherein the interpolation unit generates, by performing interpolation based on at least either of the first feature amounts and the second feature amounts obtained by an imaging process in actual imaging periods, feature amounts at imaging periods that differ from the actual imaging periods of the medical images, and wherein the display control unit displays the generated featured amounts, the first feature amounts, and the second feature amounts, which are aligned on a time axis on the display unit.
