Reconstructing Persistent Worlds from Narratives for Narrative-Grounded Interactive Experiences

从叙事中重构持久世界以实现基于叙事的交互体验

Abstract: Designing narrative-grounded interactive experiences remains labor-intensive because interactive content must align with the underlying world implied by the narrative. Existing approaches formulate problems such as narrative planning, scene generation, and gameplay generation, each constructing computational representations tailored to specific downstream tasks rather than explicitly reconstructing and maintaining the persistent world that grounds them.

摘要： 设计基于叙事的交互体验仍然是一项劳动密集型工作，因为交互内容必须与叙事所隐含的底层世界保持一致。现有的方法通常将问题归纳为叙事规划、场景生成和游戏玩法生成等，每种方法都构建了针对特定下游任务的计算表示，而不是显式地重构和维护作为其基础的持久世界。

We investigate reconstructing explicit persistent worlds from narrative descriptions as the central computational objective for narrative-grounded interactive realization. Rather than treating the world as an implicit by-product of downstream generation, our approach reconstructs and maintains persistent entities, locations, semantic relationships, and evolving world states while inferring only the contextual information required to support coherent interactive experiences.

我们研究了从叙事描述中重构显式持久世界的方法，将其作为实现基于叙事的交互体验的核心计算目标。我们的方法不再将世界视为下游生成的隐式副产品，而是重构并维护持久的实体、位置、语义关系以及不断演变的世界状态，同时仅推断支持连贯交互体验所需的上下文信息。

To investigate this perspective, we develop a reference prototype that reconstructs structured persistent world representations from narrative descriptions and subsequently instantiates playable tile-based environments. Through three representative case studies spanning a procedural scenario, an original fantasy narrative, and an adapted public-domain story, we demonstrate the feasibility of reconstructing persistent worlds and show how a shared world representation supports coherent gameplay while remaining grounded in the source narrative.

为了验证这一视角，我们开发了一个参考原型，它能从叙事描述中重构结构化的持久世界表示，并随后实例化可游玩的基于瓦片（tile-based）的环境。通过涵盖程序化场景、原创奇幻叙事和改编公有领域故事的三个代表性案例研究，我们证明了重构持久世界的可行性，并展示了共享的世界表示如何在保持与源叙事紧密联系的同时，支持连贯的游戏体验。

By explicitly reconstructing persistent worlds prior to interactive realization, this work bridges computational narrative understanding and interactive content generation, providing a semantic foundation for AI-assisted game authoring, mixed-initiative design, educational simulations, and narrative-grounded interactive experiences.

通过在交互实现之前显式地重构持久世界，这项工作架起了计算叙事理解与交互内容生成之间的桥梁，为人工智能辅助游戏创作、混合主动设计、教育模拟以及基于叙事的交互体验提供了语义基础。
