Delayed roles with authorable continuity in plan-based interactive storytelling

Abstract

We present a plan-based story generator that allows authors to ensure continuity over the entities in a story without committing to which entities will fulfill the story’s roles. By combining the ideas of authorable continuity and delayed role assignment in a plan-based storytelling context, our solution obtains benefits from both and mitigates some disadvantages. We introduce two notions of soundness for solutions that combine these ideas and then prove the soundness of our approach.
