One of the major themes to emerge in interactive narrative research is authorability and authorial intent. With interactive narratives, the human author is not present at run-time. Thus authoring interactive narratives is often a process of anticipating user actions in different contexts and using computational mechanisms and data structures for responding to the participant. Generative approaches to interactive narrative, in which an automated narrative generation system assumes some of the authoring responsibility, further decouple the human designer from the participants experience. We describe a general mechanism, called author goals, which can be used by human authors to assert authorial intent over generative narrative systems.
