Abstract

This paper presents a visual editor which supports authors to define the narrative macrostructure of non-linear interactive dramas. This authoring tool was used to represent Propp's narrative macrostructure of Russian fairy tales in non-linear plot graphs. Moreover, Propp's thorough characterization of basic narrative constituents by explanations, discussions and examples of their different realizations in his corpus is utilized to construct an automatic classification model. A semi-automatic classification supports (i) authors to associate new scenes with basic narrative constituents and (ii) players to control the narrative flow in the story engine. For the latter task, the selection of an appropriate plot element and behavioral pattern within the dialog model in response to player interactions is controlled by similarities between stimuli and known realizations of basic narrative constituents or behavioral patterns. This approach tackles the main challenge of interactive drama — to balance interactivity and storyness.
