Title: RECOMMENDATION DEVICE, RECOMMENDATION METHOD, PROGRAM, AND RECORDING MEDIUM
Abstract:
When a review which a shopper has registered in a digital marketplace is published with first content, a first estimation unit (101) estimates, from the first content, a first approval rating with regard to a shop at which the shopper made a purchase and a product which the shopper purchased at the shop. When the review is updated by the shopper with second content and published, a second estimation unit (102) estimates, from the second content, a second approval rating with regard to the shop at which the shopper made the purchase and the product which the shopper purchased at the shop. If the second approval rating is an improvement with respect to the first approval rating, a determination unit (103) increases a support recommendation score with respect to the product. If the support recommendation score with respect to the product is greater than or equal to a prescribed recommendation threshold, a recommendation unit (104) recommends, to each shop of a plurality of shops which sell the product, that each said shop carry out support with regard to the shopper who has published a review with regard to each said shop and said product in which: the first approval rating has been estimated; the first approval rating is less than a prescribed approval rating threshold; and the second approval rating has not been estimated.
