Abstract
Provided is a similarity calculation system for equalizing the time for calculating a similarity between target vectors and a query vector. The similarity calculation system includes target vector acquisition part for acquiring a plurality of target vectors, and clustering part for clustering the plurality of target vectors based on a calculation amount to be estimated for each of the plurality of target vectors, the calculation amount being estimated when calculating a similarity between each of the plurality of target vectors and a given reference query vector, so that a difference in total calculation amount for a similarity between all of the target vectors belonging to each of a plurality of clusters and the given reference query vector among the plurality of clusters decreases.
