Abstract

A search device includes a suggestion word presentation unit that presents a suggestion word based on the presentation priority by acquiring a suggestion word according to an input search string and a presentation priority from a suggestion word database, the suggestion word database storing the suggestion word and the presentation priority of the suggestion word associated to be searched by the input search string, a time information management unit that calculates time difference between a time when a search is performed and a time when a predetermined purchase operation or purchase preliminary operation is performed on a product which is related to the search and a priority management unit that updates the presentation priority stored in the suggestion word database to raise a presentation priority, which is associated with a suggestion word used for a search, higher as the time difference is smaller.

First claim

1 - 11 . (canceled)

12 . A search device comprising:
a suggestion word presentation unit configured to present a suggestion word based on the presentation priority by acquiring a suggestion word according to an input search string and a presentation priority from a suggestion word database, the suggestion word database storing the suggestion word and the presentation priority of the suggestion word associated to be searched by the input search string; a time information management unit configured to calculate time difference between a time when a search is performed and a time when a predetermined purchase operation or purchase preliminary operation is performed on a product which is related to the search; and a priority management unit configured to update the presentation priority stored in the suggestion word database to raise a presentation priority, which is associated with a suggestion word used for a search, higher as the time difference is smaller.

13 . The search device according to claim 12 , wherein
the priority management unit is configured to update the presentation priority using the time difference based on a user action performed in a predetermined period, the time difference being acquired by the time information management unit.

14 . The search device according to claim 12 , wherein
the time information management unit is configured to calculate the time difference based on a log regarding a search and a log regarding a purchase operation or a purchase preliminary operation.

15 . The search device according to claim 14 , wherein
when the log regarding the purchase operation or the purchase preliminary operation is detected, the time information management unit is configured to search a log regarding a search performed before the purchase operation or the purchase preliminary operation, and the time information management unit is configured to calculate the time difference based on the log regarding the purchase operation or the purchase preliminary operation and the log regarding the search.

16 . The search device according to claim 14 , wherein
the time information management unit is configured to:
acquire user information and product information included in the log regarding the purchase operation or the purchase preliminary operation;
search a log regarding a search having identical user information and identical product information; and
calculate the time difference based on the log regarding the purchase operation or the purchase preliminary operation and the log regarding the search.

17 . The search device according to claim 12 , wherein
the suggestion word database includes a plurality of presentation priorities associated with each suggestion word, and the suggestion word presentation unit is configured to acquire at least one presentation priority selected from a plurality of presentation priorities.

18 . The search device according to claim 17 , wherein
the suggestion word database stores a presentation priority for each user attribute as a plurality of presentation priorities indicative of a user attribute who performs a search, and the suggestion word presentation unit is configured to select and acquire a presentation priority according to the user attribute of the user who performs the search.

19 . The search device according to claim 17 , wherein
the suggestion word database stores a presentation priority for each product category as a plurality of presentation priorities, and the suggestion word presentation unit is configured to select and acquire a presentation priority according to a product category selected during a search.

20 . A search method performed by a processing unit, the search method comprising:
presenting a suggestion word based on the presentation priority by acquiring a suggestion word according to an input search string and a presentation priority from a suggestion word database, the suggestion word database storing the suggestion word and the presentation priority of the suggestion word associated to be searched by the input search string; calculating time difference between a time when a search is performed and a time when a predetermined purchase operation or purchase preliminary operation is performed on a product which is related to the search; and updating the presentation priority stored in the suggestion word database to raise a presentation priority, which is associated with a suggestion word used for a search, higher as the time difference is smaller.

21 . A non-transitory storage medium for storing a program configured to cause a processing unit to perform:
a suggestion word presentation processing configured to present a suggestion word based on the presentation priority by acquiring a suggestion word according to an input search string and a presentation priority from a suggestion word database, the suggestion word database storing the suggestion word and the presentation priority of the suggestion word associated to be searched by the input search string; a time difference computation processing configured to calculate time difference between a time when a search is performed and a time when a predetermined purchase operation or purchase preliminary operation is performed on a product which is related to the search; and a presentation priority update processing configured to update the presentation priority stored in the suggestion word database to raise a presentation priority, which is associated with a suggestion word used for a search, higher as the time difference is smaller.
