Outline of Annual Research Achievements

言語をベースにした感情解析の研究はまだ初期段階にある．本研究では，研究代表者が過去に開発した感情解析システム及び感情の文脈的適切性判定手法などの技術を融合し，話者の感情状態を読み取り会話の場面に柔軟に順応する言語モデルを構築した．これを以前開発した大規模自然言語コーパスに適応し会話内の感情の働きを明らかにすることに貢献した．また，構築モデルを対話エージェントへ導入し，ネット上のいじめの対策という実世界問題へ応用した．話者（掲示板参加者など）の会話中に起こる急な変化（怒り，落ち込み等）に着目し，いじめの行動を発見することが可能となったため，今後その技術を応用することによってネットいじめ被害者数の減少に貢献することが期待される．
