AI 中文摘要
设计基于叙事的交互体验仍然需要大量人力，因为交互内容必须与叙事所隐含的底层世界保持一致。现有方法将问题表述为叙事规划、场景生成和游戏玩法生成等任务，每种方法都构建了针对特定下游任务定制的计算表示，而非显式重建和维护作为这些任务基础的持久世界。我们研究将从叙事描述中重建显式持久世界作为实现基于叙事的交互的核心计算目标。我们的方法不将世界视为下游生成的隐性副产品，而是重建并维护持久实体、位置、语义关系和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。为验证这一思路，我们开发了一个参考原型，该原型从叙事描述中重建结构化的持久世界表示，随后实例化可游玩的基于图块的环境。我们通过涵盖程序场景、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，证明了重建持久世界的可行性，并展示了共享世界表示如何在保持与源叙事一致的同时支持连贯的游戏玩法。这项工作通过在交互实现前显式重建持久世界，弥合了计算叙事理解与交互内容生成之间的差距，为AI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。
英文摘要
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. 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. 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. 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.
