背景史と感情の因子分析に基づく背景史の役割の解明 Elucidating the Role of Background Histories Based on Factor Analysis of Background Histories and Emotions 坂本, 珠凜 村井, 源 Jurin, Sakamoto Hajime, Murai 物語の登場人物には物語本編より過去の時系列の物語が設定され，その開示によって読者や他の登場人物に同一化や共感を促すことが多々ある．本研究では登場人物が持つ物語本編より過去の時系列の物語を背景史と定義し，作品間の背景史と感情の関係性の解明のため，χ二乗検定と残差分析による背景史の出現頻度の比較分析を実施した．また，物語における背景史の役割の解明のため，背景史と感情の因子分析によって 8 種類の因子を抽出した．因子分析の結果から，登場人物の精神状態や行動選択に影響を与える要因として，不幸やすれ違いがもたらした悲劇的な背景史などの複数のパターンが明らかになった． In many cases, the characters in a story have stories from the past, and the disclosure of these stories often leads readers and other characters to identify with or sympathize with them. In this study, we defined background histories as a time-series of stories that the characters have in the past from the main story, and conducted a comparative analysis of the frequency of occurrence of background histories by χ-squared test and residuals analysis in order to clarify the relationship between background histories and emotions in different works. In addition, to clarify the role of background histories in the story, eight factors were extracted through factor analysis of background histories and emotions. The results of the factor analysis revealed several patterns of factors that influence the mental states and behavioral choices of the characters, such as tragic background histories caused by misfortunes and misunderstandings. 情報処理学会 2024-02-10 jpn technical report https://ipsj.ixsq.nii.ac.jp/records/232359 2188-8957 AN1010060X 研究報告人文科学とコンピュータ（CH） 2024-CH-134 1 1 7 https://ipsj.ixsq.nii.ac.jp/record/232359/files/IPSJ-CH24134001.pdf application/pdf 532.8 kB 2026-02-10
