摘要

A feature amount calculation means uses N feature amount functions, for obtaining feature amounts for data from said data, to calculate N feature amounts for first data and N feature amounts for second data. A degree of similarity calculation means calculates the degree of similarity between the first data and the second data on the basis of the N feature amounts for the first data and the N feature amounts for the second data. Values for the N feature amounts obtained when the same data is substituted into the N feature value amount functions are different from each other.
