Abstract

An obtaining unit ( 120 ) obtains a ranking of a commercial product belonging to a category defined on an e-marketplace. A collecting unit ( 121 ) collects a term relevant to a commercial product at an upper position in the obtained ranking from a text contained in a sales page for selling the upper ranking position commercial product or a search query that triggers the sales page to be viewed. A calculating unit ( 122 ) calculates a score of each collected term based on at least a number of collections of the term. A presenting unit ( 123 ) presents, as a suggested keyword for search refinement of the commercial product belonging to the category, the term with the calculated score in an upper ranking position.

First claim

1 . An information providing device comprising:
an obtaining unit that obtains a ranking of a commercial product belonging to a category defined on an e-marketplace; a collecting unit that collects a term relevant to a commercial product at an upper position in the obtained ranking from a text contained in a sales page for selling the upper ranking position commercial product or a search query that triggers the sales page to be viewed; a calculating unit that calculates a score of each collected term based on at least a number of collections of the term; and a presenting unit that presents, as a suggested keyword for search refinement of the commercial product belonging to the category, the term with the calculated score at an upper ranking position, wherein: in the e-marketplace, a category hierarchy is defined by a tree structure with each category disposed at a node; and the score of the collected term for the category is defined based on a product of: (a) a weighting defined by the number of collections of the term; and (b) a contrary category frequency defined by a number of child categories of the category, and a number of child categories where the term is collected among the child categories.

2 . (canceled)

3 . An information providing device comprising:
an obtaining unit that obtains of a commercial product belonging to a category defined on a e-marketplace; a collecting unit that collects a term relevant to a commercial product at an upper position in the obtained ranking from a text contained in a sales page for selling the upper ranking position commercial product or a search query that triggers the sales page to be viewed; a calculating unit that calculates a score of each collected term based 5 on at least a number of collections of the term; and a presenting unit that presents, as a suggested keyword for search refinement of the commercial product belonging to the category, the term with the calculated score at an upper ranking position, wherein: the score of the collected term for the category is defined based on a value obtained by decreasing the number of collections of the term for the category on a basis of a number of collections of the term in another category.

4 . The information providing device according to claim 3 , wherein:
a higher a similarity between the category and the other category is, a smaller a degree of decrease is.

5 . The information providing device according to claim 3 , wherein:
in the e-marketplace, a category hierarchy is defined by a tree structure with each category disposed at a node; and in the tree structure, when the category and the other category are brotherhood categories, a similarity between the category and the other category is high.

6 . The information providing device according to claim 3 , wherein:
in the e-marketplace, a category hierarchy is defined by a tree structure with each category disposed at a node; and in the tree structure, when a distance between the category to the other category is short, a similarity between the category and the other category is high.

7 . The information providing device according to claim 1 , wherein:
in the e-marketplace, each of a plurality of shops creates the sales page, and the same commercial product belonging to the same category are available from the respective sales pages; and the ranking is obtained for each category to which the sold commercial product belongs regardless of from which shop the commercial product is sold.

8 . An information providing method executed by an information providing device including an obtaining unit, a collecting unit, a calculating unit, and a presenting unit, the method comprising:
obtaining by the obtaining unit a ranking of a commercial product belonging to a category defined on an e-marketplace; collecting by the collecting unit a term relevant to a commercial product at an upper position in the obtained ranking from a text contained in a sales page for selling the upper ranking position commercial product or a search query that triggers the sales page to be viewed; calculating by the calculating unit a score of each collected term based on at least a number of collections of the term; and presenting by the presenting unit, as a suggested keyword for search refinement of the commercial product belonging to the category, the term with the calculated score at an upper ranking position, wherein: in the e-marketplace, a category hierarchy is defined by a tree structure with each category disposed at a node; and the score of the collected term for the category is defined based on a product of : (a) a weighting defined by the number of collections of the term; and (b) a contrary category frequency defined by a number of child categories of the category, and a number of child categories where the term is collected among the child categories.

11 . An information providing method executed by an information providing device including an obtaining unit, a collecting unit, a calculating unit, and a presenting unit, the method comprising:
obtaining by the obtaining unit a ranking of a commercial product belonging to a category defined on an e-marketplace; collecting by the collecting unit a term relevant to a commercial product at an upper position in the obtained ranking from a text contained in a sales page for selling the upper ranking position commercial product or a search query that triggers the sales page to be viewed; calculating by the calculating unit a score of each collected term based on at least a number of collections of the term; and presenting by the presenting unit, as a suggested keyword for search refinement of the commercial product belonging to the category, the term with the calculated score at an upper ranking position, wherein: the score of the collected term for the category is defined based on a value obtained by decreasing the number of collections of the term for the category on a basis of a number of collections of the term in another category.

12 . The information providing device according to claim 1 , wherein:
the score of the collected term for the category is defined based on a value obtained by decreasing the number of collections of the term for the category on a basis of a number of collections of the term in another category.
