Summary:To identify zero pronouns in an input sentence using a more simplified mechanism as compared with a conventional art.SOLUTION: A zero pronoun identifying device comprises: a word dividing unit that divides an input sentence; a predicate identifying unit that identifies a predicate from the sentence divided into words by the word dividing unit; and a zero pronoun identifying unit that calculates a span of an item for the predicate using a zero pronoun identifying model which is a model in which an output layer is added to a trained language model, determines whether or not an empty category exists by comparing a score of the span with a score of the empty category for the predicate, and if the empty category exists, determines presence or absence of a zero pronoun by classifying the empty category.SELECTED DRAWING: Figure 1 【課題】従来よりも簡単な仕組みで入力文のゼロ代名詞を同定する。【解決手段】ゼロ代名詞同定装置において、入力された文を分割する単語分割部と、前記単語分割部により単語分割された前記文から述語を同定する述語同定部と、訓練済み言語モデルに出力層を追加したモデルであるゼロ代名詞同定モデルを用いて、前記述語に対する項のスパンを求め、前記スパンのスコアと、前記述語に対する空範疇のスコアとを比較することにより、前記空範疇が存在するかどうかを判定し、前記空範疇が存在する場合に、前記空範疇を分類することによりゼロ代名詞の有無を判定するゼロ代名詞同定部とを備える。【選択図】図1
