アニメーションは主要なエンタテインメントコンテンツの一つとして認知されているが，その制作過程で生成される中間生成物は作品が完成した直後に廃棄されることが多い．我々はこれを文化的損失と捉え，中間生成物を蓄積・保存するインセンティブ創出のために，アイデアソンを通じてそれらの活用可能性を検討した．その結果，(1) 中間生成物の横断的検索の必要性，(2) 機械学習用リソースとしての活用，(3) 新たな表現メディア創出の手がかり，という3つの観点を得た．
Although anime is recognized as one of the primary entertainment content in Japan, the intermediate products generated during the production process are often discarded immediately after completing the work. We considered the discarding as a cultural loss and examined the possibility of their utilization. We conducted an ideathon to explore incentives to accumulate and preserve the intermediate products. As a result, we obtained three viewpoints: the need for a cross-sectional search of intermediate products, their use as training data for generative deep learning technologies, and clues for creating new expressive media.
