To properly determine an aggregation unit.SOLUTION: An information processing device 10 determines an aggregation unit for indicating a unit of time interval when time series data 11a is aggregated in a time axis direction. A processing unit 12 acquires an amount of data after aggregation when each of a plurality of aggregation units are used and an index indicating a degree of variations of a value of the time series data 11a for each of the plurality of aggregation units. The processing unit 12 determines the aggregation unit used for aggregating the time-series data 11a among the plurality of aggregation units based on the amount of data acquired for each of the plurality of aggregation units and the index.SELECTED DRAWING: Figure 1 【課題】集計単位を適切に決定する。【解決手段】情報処理装置１０は、時系列データ１１ａを時間軸方向に集計する際の時間間隔の単位を示す集計単位を決定する。処理部１２は、複数の集計単位それぞれを用いた場合の集計後のデータのデータ量と、複数の集計単位それぞれに対する時系列データ１１ａの値のばらつきの度合いを示す指標とを取得する。処理部１２は、複数の集計単位それぞれに対して取得したデータ量と当該指標とに基づいて、複数の集計単位のうち時系列データ１１ａの集計に用いる集計単位を決定する。【選択図】図１
