Abstract

Recent advances in large language models (LLMs) have enabled social simulation through multi-agent systems.
Prior efforts focus on agent societies created from scratch, assigning agents with newly defined personas. However, simulating established fictional worlds and characters remain largely underexplored, despite its significant practical value. In this paper, we introduce BookWorld, a comprehensive system for constructing and simulating book-based multi-agent societies. BookWorld’s design covers comprehensive real-world intricacies, including diverse and dynamic characters, fictional worldviews, geographical constraints and changes, e.t.c. BookWorld enables diverse applications including story generation, interactive games and social simulation, offering novel ways to extend and explore beloved fictional works. Through extensive experiments, we demonstrate that BookWorld generates creative, high-quality stories while maintaining fidelity to the source books, surpassing previous methods with a win rate of 75.36%.

Introduction: The first system for constructing fiction-based multi-agent societies

Recent advances in LLMs have enabled social simulation through multi-agent systems. Prior efforts focus on agent societies created from scratch, assigning agents with newly defined personas. However, simulating established fictional worlds and characters remain largely underexplored, despite its significant practical value. In our paper titled “BookWorld: From Novels to Interactive Agent Societies for Creative Story Generation”, we introduce BookWorld, a comprehensive system for constructing and simulating book-based multi-agent societies.

The Overview of BookWorld

BookWorld provides a complete pipeline from data collection to social simulation, and finally, rephrasing into novelistic text.

Data Extraction

Before the simulation starts, we extract character and worldview data from source materials, used for book-to-system construction.

Simulation

The simulation begins by initializing role agents and the world agent, loading character profiles, the geospatial map, the worldview data and other necessary information.

Rephrasing

After the simulation ends, we collect the simulation records and apply LLMs to rephrase the records into the final, novel-style story.
