GENRE GENERATION DEVICE, NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM STORING GENRE GENERATION PROGRAM, AND GENRE GENERATION METHOD

摘要

A genre generation device (200) includes a calculating part (235) that calculates a co-occurrence level of a first keyword representing a first genre to be generated and a second keyword representing a second genre that is an attended genre in a search query in a genre hierarchy, and a generating part (265) that generates the first genre in a different layer from a layer where the second genre belongs when a difference between the co-occurrence level of the first keyword and the second keyword, and, a threshold for a level is smaller than a threshold for a disparity.

1. A genre generation device comprising:
an obtaining part that obtains a search query for searching at least one product or at least one service; a generating part that generates a genre where the at least one product or the at least one service is classified; and a calculating part that calculates a level of co-occurrence of a first keyword and a second keyword in the obtained search query, the first keyword representing a first genre that is a genre to be generated, and the second keyword representing a second genre that is an attended genre in a genre hierarchy constructed by a plurality of genres, wherein when a disparity between the calculated level of co-occurrence of the first keyword and the second keyword, and, a level threshold that is a threshold for a level is smaller than a disparity threshold that is a threshold for a disparity, the generating part generates, in the genre hierarchy, the first genre as a different-layer genre belonging to a different layer from a layer where the second genre represented by the second keyword belongs.
