摘要

To determine that a local spot is a local spot with high accuracy and to judge a major spot as a major spot with high accuracy.A spot determination apparatus 100 includes a spot frequency acquisition unit 1 that acquires a spot frequency indicating a frequency at which a designated spot appears in a predetermined document group, a spot frequency acquisition unit 1 that acquires a spot and an address of the spot A co-occurrence frequency acquisition unit 2 that acquires a co-occurrence frequency indicating a frequency of occurrence of co-occurrence between the spot frequency and the co-occurrence frequency of each level included in the level, the spot frequency, the co-occurrence frequency, A popularity calculating section 3 for calculating the degree of recognition of a plurality of ranges of the spot using the frequency of appearance of the spot and a local score calculating section 4 for calculating the local score of the spot by using the degree of recognition of the plurality of ranges.BACKGROUND OF THE INVENTION
