To organize groups of talk flows included in a text of dialogue into information with high visibility.SOLUTION: A dialogue context analysis system 60 includes: a talk flow extraction unit 64 which groups a plurality of contexts represented with transition of a subject in a speech text D61 on the basis of inter-group similarity which is a degree of similarity between groups composed of subjects, and creates a representative context that represents a representative context in the group with transition of the subject; a branched talk flow generation unit 65 which defines a subject included in common in multiple representative contexts as a branched subject, and associates the representative contexts with the branched subject; and a user interface unit 67 which displays the subjects of the representative contexts and transition of the subjects, using a single subject object which is an image object representing a subject of a single representative context, a branched subject object which is an image object representing a branched subject, and a transition object which is an image object representing transition of the subject.SELECTED DRAWING: Figure 15 【課題】会話のテキストに含まれるトークフローのグループを視認性の高い情報に整理する。【解決手段】会話文脈解析システム６０は、発話テキストＤ６１の話題の遷移により表される複数の文脈を、話題を要素とする集合同士の類似度である集合間類似度に基づいてグループ化し、グループの代表的な文脈を話題の遷移により示す代表文脈を作成するトークフロー抽出部６４と、複数の代表文脈に共通に含まれる話題を分岐点話題とし、複数の代表文脈同士を分岐点話題にて関連づける分岐型トークフロー生成部６５と、単独の代表文脈の話題を表す画像オブジェクトである単独話題オブジェクトと、分岐点話題を表す画像オブジェクトである分岐点話題オブジェクトと、話題の遷移を表す画像オブジェクトである遷移オブジェクトとによって、複数の代表文脈の話題およびその遷移を表示するユーザインタフェース部６７と、を有する。【選択図】図１５
