Abstract

It is possible to accurately grasp the taste of each user and provide information in which the taste thereof is accurately reflected. Store information kept in a store information storage unit (100) is provided to each user. User taste information (T) including the values of taste on feature items of each genre is stored for each user in a user taste information storage unit (110). Store evaluation information (E) including the values of evaluation on the feature items of its genre is stored for each store in a store evaluation information storage unit (120). A store information providing unit (130) selects store information having the store evaluation information (E) matched with the user taste information (T) and provides it to the user. If the user views specific store information or utilizes a specific store, the specific store is recoded in a target store recording unit (150) as a target store. A taste value updating unit (140) updates the user taste information (T) on the basis of the store evaluation information (E) of the accumulated target store.
