Selecting device and selecting method

Abstract

A calculation unit (15a) calculates a degree of similarity between each of training data candidates that are documents to which predetermined tags corresponding to descriptions therein have been added and test data that is a document to which tags are to be added, a selection unit (15b) selects, as training data, a training data candidate of which the degree of similarity thus calculated is no less than a predetermined threshold value, and an addition unit (15c) performs learning using the training data thus selected, and adds the tags to the test data according to a result of learning. The calculation unit (15a) may calculate the degree of similarity by using the frequency of appearance of a predetermined word that appears in the training data candidates and the test data. The calculation unit (15a) may calculate the degree of similarity by using the frequency of appearance of a predetermined word in each of the tags added to training data candidates.
