Adaptive Generation of Dilemma-based Interactive Narratives

In this paper we present a system which automatically generates interactive stories that are focused around dilemmas to create dramatic tension. A story designer provides the background of the story world, such as information on characters and their relations, objects, and actions. In addition, our system is provided with knowledge of generic story actions and dilemmas which are based on those clichés encountered in many of today’s soap operas. These dilemmas and story actions are instantiated for the given story world and a story planner creates sequences of actions that lead to dilemmas. The player interacts with the story by making decisions on these dilemmas. Using this input, the system adapts future story lines according to the player’s preferences.
