Informing a BDI Player Model for an Interactive Narrative
Jessica Rivera-Villicana, Fabio Zambetta, James Harland, Marsha Berry

TL;DR
This paper develops a BDI-based player model for interactive narratives, using player profiles derived from observed behavior to improve simulation accuracy, though self-assessment data proved unreliable.
Contribution
It introduces a method to create player profiles from observed interactions to enhance BDI player models in interactive fiction.
Findings
Player profiles can improve BDI model performance.
Self-assessment data was unreliable for profile creation.
Qualitative and quantitative evaluations support the approach.
Abstract
This work focuses on studying players behaviour in interactive narratives with the aim to simulate their choices. Besides sub-optimal player behaviour due to limited knowledge about the environment, the difference in each player's style and preferences represents a challenge when trying to make an intelligent system mimic their actions. Based on observations from players interactions with an extract from the interactive fiction Anchorhead, we created a player profile to guide the behaviour of a generic player model based on the BDI (Belief-Desire-Intention) model of agency. We evaluated our approach using qualitative and quantitative methods and found that the player profile can improve the performance of the BDI player model. However, we found that players self-assessment did not yield accurate data to populate their player profile under our current approach.
