IBSEN: Director-Actor Agent Collaboration for Controllable and Interactive Drama Script Generation

TL;DR

IBSEN introduces a director-actor framework using large language models to generate controllable, diverse, and character-consistent drama scripts based on user-defined plot outlines and interactive scenario adjustments.

Contribution

This work presents a novel director-actor agent framework that enhances controllability and interactivity in drama script generation using large language models.

Findings

Generated complete, diverse drama scripts from rough plot outlines.

Maintained character consistency in generated scripts.

Effective interaction and plot adjustment with human participation.

Abstract

Large language models have demonstrated their capabilities in storyline creation and human-like character role-playing. Current language model agents mainly focus on reasonable behaviors from the level of individuals, and their behaviors might be hard to constraint on the level of the whole storyline. In this paper we introduce IBSEN, a director-actor coordinate agent framework that generates drama scripts and makes the plot played by agents more controllable. The director agent writes plot outlines that the user desires to see, instructs the actor agents to role-play their characters, and reschedules the plot when human players participate in the scenario to ensure the plot is progressing towards the objective. To evaluate the framework, we create a novel drama plot that involves several actor agents and check the interactions between them under the instruction of the director agent. Evaluation results show that our framework could generate complete, diverse drama scripts from only a rough outline of plot objectives, meanwhile maintaining the characteristics of characters in the drama.
