Zusammenfassung:An information processing device 1 includes an antecedence quantification unit 11 configured to obtain a scalar vij that quantifies a cross-correlation function between time-series data of items, a similarity calculation unit 12 configured to obtain a semantic similarity uij indicating semantic closeness between the items, and an unexpectedness calculation unit 13 configured to obtain unexpectedness of a combination of the items on the basis of a position of a point indicating the combination of the items on a plane having the scalar vij and the semantic similarity uij as axes.
