Story Planning as Exploratory Creativity : Techniques for Expanding the Narrative

The authoring of fictional stories is considered a creative process. The purpose of most story au-thoring is not to invent a new style or genre of story that will be accepted by the population but to invent a single narrative that is novel enough to be tellable. Computational story generation systems are more limited in the space of narratives than human authors because it is often the case that a story generation system is constrained to operate within a fixed representation of the story world. These limitations can impact whether a story generation system is considered creative or not. In this paper, we describe a story planning system, Fabu-list. Fabulist however is constrained by the world model input by the system user. We present two algorithms that enable story planning system such as Fabulist to break outside the bounds of the initial world model in order to search a larger space of narratives.
