摘要： Movie analysis is an umbrella term for many tasks aiming to automatically interpret, extract, and summarize the content of a movie. Potential applications include generating shorter versions of scripts to help with the decision making process in a production company, enhancing movie recommendation engines, and notably generating movie previews. In this talk I will introduce the task of turning point identification as a means of analyzing movie content. According to screenwriting theory, turning points (e.g., change of plans, major setback, climax) are crucial narrative moments within a movie: they define its plot structure, determine its progression and segment it into thematic units. I will argue that turning points and the segmentation they provide can facilitate the analysis of long, complex narratives, such as screenplays. I will further formalize the generation of a shorter version of a movie as the problem of identifying scenes with turning points and present a graph neural network model for this task based on linguistic and audiovisual information. Finally, I will discuss why the representation of screenplays as (sparse) graphs offers interpretability and exposes the morphology of different movie genres.
