Abstract
An information processing device includes an extracting unit, a first calculating unit, and a second calculating unit. From a sentence included in a set of sentences, the extracting unit extracts compound words, each made of a plurality of words, and first words other than the words constituting the compound words. The first calculating unit calculates, based on the occurrence frequencies of the first words and based on the occurrence frequencies of the compound words, first degrees of importance indicating the degrees of importance of the first words and the degrees of importance of the compound words. With respect to first sentences included in the set of sentences, the second calculating unit calculates second degrees of importance, which indicate the degrees of importance of the first sentences, based on the first degrees of importance of the words and the first degrees of importance of the compound words.
