抄録
内容記述タイプ Abstract
内容記述 質問応答システムによって収集された大量のユーザ質問文を含むコーパス中から換喩表現とその解釈表現を自動抽出し,それを質問応答システム「ダイアログナビ」におけるユーザ質問文とテキストのマッチングに応用する方法を提案する.具体的には,換喩表現(例: GIF を表示する) とその解釈表現(例: GIF の画像を表示する) のペアをダイアログナビの同義表現辞書に登録することによって,ユーザ質問文とテキスト文の間の係り受け関係のずれを解消する.抽出された換喩表現・換喩解釈表現ペアについて評価を行ったところ,大半は適切なものであった.また,テストセットを用いて実験を行った結果,提案手法がマッチング精度を改善することがわかった.

内容記述タイプ Abstract
内容記述 This paper proposes a method of extracting metonymic expressions and their interpretative expressions from corpora and its application to the full-parsing-based matching method of a QA system Dialog Navigator. Namely, our method resolves modifier-head relation gaps between user questions and texts, by registering pairs of metonymic expressions (e.g. “display a GIF”) and interpretative expressions (e.g. “display a GIF file”) into the synonymous expression dictionary of Dialog Navigator. An evaluation showed that most of the extracted interpretations were correct, and an experiment using testsets indicated that introducing the metonymic expressions significantly improved the performance of our system.
