Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an information processing device and an information processing program, when compiling what kind of a subject is contained and a ratio of a subject occupying the respective sentence in plural sentences in which respective subjects are described, capable of extracting a detail subject as compared with a case in which a subject is extracted using a morpheme included in a cluster formed by one stage clustering.SOLUTION: The information processing device comprises: formation means 42 for forming, from a co-occurrence network indicating relevancy of plural morphemes included in plural sentences, plural clusters containing related plural morphemes; and extraction means 44 for extracting a subgraph containing plural morphemes satisfying a predetermined condition which indicates mutual relevancy, from each of the plural clusters formed by the formation means 42.SELECTED DRAWING: Figure 3
【課題】各々課題が記された複数の文章の中に、どのような課題がどの程度含まれているかを集計する際、1段階のクラスタリングにより形成されたクラスタに含まれる形態素を用いて課題を抽出する場合と比較して、より具体的な課題を抽出することができる情報処理装置及び情報処理プログラムを提供する。【解決手段】複数の文章に含まれる複数の形態素の関連性を示す共起ネットワークから、各々関連する複数の形態素を含む複数のクラスタを形成する形成手段42と、形成手段42により形成された複数のクラスタの各々から、相互の関連性を示す予め定めた条件を満たす複数の形態素を含むサブグラフを抽出する抽出手段44と、を備える。【選択図】図3 |
