Abstract
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.
Claims17
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.
(canceled)
A non-transitory computer-readable recording medium having stored therein a genre generation program that allows a computer to function as:
- 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.
A genre generation method executed by a genre generation device comprising an obtaining part, a generating part, and a calculating part, this genre generation method comprising:
- an obtaining step in which the obtaining part obtains a search query for searching at least one product or at least one service;
- a generating step in which the generating part generates a genre where the at least one product or the at least one service is classified;
- and
- a calculating step in which the calculating part 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, in the generating step, the generating part generates the first genre in the genre hierarchy as a different-layer genre belonging to a different layer from a layer where the second genre represented by the second keyword belongs.
