The conventional story analysis targets a specific genre, and few research has been conducted to quantitatively clarify the differences between genres. In this study, in order to realize a cross-genre story structure analysis, more than 1500 episodes were collected for 5 genres (adventure, combat, love, detective, ghost story) that frequently appear in contemporary Japanese entertainment works. We also constructed a data set that can be compared by structurally analyzing all genres in a common framework. Based on the genre data set, common and unique factors of story plot were identified by factor analysis. Moreover, the structural characteristics of sub-genre were extracted by utilizing cluster analysis. Since the characteristics of each genre can be compared based on the same criteria, it is expected that the analysis and automatic generation of complex genre stories will be executed in the future.
