IVIE: A Neuro-symbolic Approach to Incremental and Validated Generation of Interactive Fiction Worlds

IVIE (Incremental & Validated Interactive Experiences) is a neuro-symbolic framework for generating interactive fiction worlds, integrating a four-stage incremental generation pipeline that combines large language models (LLMs) for creative elements with symbolic validation for coherence. The system produces interconnected locations, functional items, and coherent puzzles, achieving high player engagement as shown by human evaluations, while addressing challenges such as LLM inconsistencies and validation gaps. This approach highlights the potential of neuro-symbolic methods to enhance narrative coherence in AI-generated content, offering insights for future developments in interactive storytelling systems.
