Zusammenfassung:PROBLEM TO BE SOLVED: To present a candidate suiting user's taste without using his or her history.SOLUTION: A candidate presentation unit 101 presents, to a user, a plurality of candidates out of candidates included in an N-th (N is an integer equal to or larger than 1) search range. A candidate selection unit 102 selects a candidate from the plurality of presented candidates in accordance with user's operation. A search range update unit 105 updates the N-th search range to an (N+1)th search range narrower than the N-th search range on the basis of elements of the selected candidate. If the N-th search range is updated to the (N+1)th search range, the candidate presentation unit 101 presents a plurality of candidates out of candidates included in the (N+1)th search range. 【課題】履歴を使用せず、ユーザの嗜好に則した候補を提示する。【解決手段】候補提示部101は、ユーザに対して、第N(N:1以上の整数)の探索範囲に含まれる候補から複数の候補を提示する。候補選択部102は、ユーザの操作に応じて、提示された複数の候補から候補を選択する。探索範囲更新部105は、選択された候補の要素に基づいて、第Nの探索範囲から、第Nの探索範囲より狭い第N+1の探索範囲に更新する。候補提示部101は、第Nの探索範囲から第N+1の探索範囲に更新された場合、第N+1の探索範囲に含まれる候補から複数の候補を提示する。【選択図】図1
