Summary:To provide an instance retrieval device, method and program which enable retrieval with a high degree of freedom.SOLUTION: An instance retrieval device according to an embodiment comprises: a first acquisition unit; a second acquisition unit; a calculation unit; a retrieval unit; and a presentation unit. The first acquisition unit acquires a retrieval condition being data of an instance of a retrieval object. The second acquisition unit acquires a meta retrieval condition being a description about a point of view to which attention is paid when retrieving an instance similar to the retrieval condition. The calculation unit calculates the similarity between the retrieval condition and each of a plurality of reference instances being data of an instance of a retrieved object on the basis of the meta retrieval condition. The retrieval unit retrieves the similar reference instance similar to the retrieval condition at the point of view of the meta retrieval condition for the plurality of reference instances on the basis of the similarity. The presentation unit presents a retrieval result by the retrieval unit.SELECTED DRAWING: Figure 2 【課題】自由度の高い検索を可能にする事例検索装置、方法及びプログラムを提供すること。【解決手段】 実施形態に係る事例検索装置は、第1取得部、第2取得部、算出部、検索部及び提示部を有する。第1取得部は、検索対象の事例のデータである検索条件を取得する。第2取得部は、検索条件に類似する事例を検索するうえで注目する観点に関する記述であるメタ検索条件を取得する。算出部は、メタ検索条件に基づいて、検索条件と被検索対象の事例のデータである複数の参照事例各々との類似度を算出する。検索部は、類似度に基づいて、複数の参照事例に対して、メタ検索条件の観点で検索条件に類似する類似参照事例を検索する。提示部は、検索部による検索結果を提示する。【選択図】 図2
