| Outline of Final Research Achievements |
Using our Video Retrieval System for Diet Deliberations to partially play the parliamentary video clips corresponding to the minutes through keyword search, we attempt to uncover the parliamentary communication space we cannot understand by reading the written records.
We examined the chronological changes in late Prime Minister Abe’s speech style by comparing the speech recognition results and the minutes. In addition to analyzing the transition of the deliberation scene and the shift in the deliberation agenda, we developed analytical functions to connect the parliamentary deliberations with the information on legislators and related news available on the Internet. Furthermore, we utilized the video retrieval system to examine how legislators pronounce heteronyms and suggested their interactive relationship with political stance and linguistic emotion.

| Academic Significance and Societal Importance of the Research Achievements |
法案数や発言数といった数量分析から議会審議の内容分析への進展はありますが，まだ会議録偏重は根強く残っています．この研究は，書き言葉として加工された文字情報だけでなく，文字・音声・映像を統合的に分析することによって，会議録を読むだけでは解明できない発言スタイルの変化や言語的感情と発音の関係を明らかにし，新たな研究領域を開拓することに貢献しています．また，審議映像検索を可能にし，審議をダイジェスト化することは，議会情報のアクセシビリティを全般的に高めるだけでなく，視聴覚に支障がある場合でも字幕付与や音声再生によって，臨場感のある議会情報へのアクセスを保障します．
