PROBLEM TO BE SOLVED: To learn correspondence between a problem and a solution while reducing costs.SOLUTION: An interactive device according to the present invention includes a storage unit, a first extraction unit, a search unit, a generation unit, a second extraction unit, and a registration unit. The storage unit stores a problem and one or more solutions for solving the problem in correlation. The first extraction unit extracts, as a subject problem, an expression from the first utterance of a user that can be grasped to be the problem. The search unit searches the storage unit for a subject solution that is a solution to the subject problem. The generation unit generates a first utterance promotion sentence for prompting an utterance from the user that includes the subject solution, when there is not the subject solution in the storage unit or the subject solution is denied by the user. The second extraction unit extracts the subject solution from a second utterance that is a response of the user to the first utterance promotion sentence. The registration unit registers the subject problem and the subject solution in correlation in the storage unit. 【課題】コストを低減しつつ課題および解決策の対応を学習できる。【解決手段】本実施形態に係る対話装置は、格納部、第１抽出部、検索部、生成部、第２抽出部および登録部を含む。格納部は、課題と該課題を解決するための１以上の解決策とを対応付けて格納する。第１抽出部は、利用者の第１発話から、課題と捉えうる表現を対象課題として抽出する。検索部は、前記対象課題に対応する解決策である対象解決策を前記格納部から検索する。生成部は、前記格納部に前記対象解決策が存在しない場合または該対象解決策が前記利用者により拒否される場合、前記利用者から前記対象解決策を含む発話を促すための第１発話促進文を生成する。第２抽出部は、前記第１発話促進文に対する前記利用者の応答である第２発話から前記対象解決策を抽出する。登録部は、前記対象課題と前記対象解決策とを対応付けて前記格納部に登録する。【選択図】図１
