用开放框架让AI生成连贯故事，支持玩家自由互动。
Narrative Context Protocol: An Open-Source Storytelling Framework for Generative AI
- 用结构化故事模板统一叙事数据，实现跨系统复用
- 一年实验验证：基于小说改编的文本游戏可实时生成剧情
- 适合游戏开发与交互叙事研究者使用
本文介绍叙事上下文协议（Narrative Context Protocol, NCP），一个开源的叙事标准，旨在实现叙事互操作性、由AI驱动的创作工具以及实时涌现式叙事。通过将故事结构编码为“故事形式”（Storyform）——一种包含叙事特征的结构化注册表，NCP使叙事可在不同系统间迁移，并为生成式叙事系统提供基于意图的约束。我们通过为期一年的实验验证其能力：作者使用NCP和定制创作平台，基于已有短篇小说构建了一个可交互的文本体验。该体验由生成式AI驱动，支持无限制自然语言输入。NCP作为一组“护栏”，在保障玩家自主性的同时，确保叙事上下文与连贯性。
原文摘要 · Abstract (English)
Here we introduce Narrative Context Protocol (NCP), an open-source narrative standard designed to enable narrative interoperability, AI-driven authoring tools, real-time emergent narratives, and more. By encoding a story's structure in a "Storyform," which is a structured register of its narrative features, NCP enables narrative portability across systems as well as intent-based constraints for generative storytelling systems. We demonstrate the capabilities of NCP through a year-long experiment, during which an author used NCP and a custom authoring platform to create a playable, text-based experience based on her pre-existing novella. This experience is driven by generative AI, with unconstrained natural language input. NCP functions as a set of "guardrails" that allows the generative system to accommodate player agency while also ensuring that narrative context and coherence are maintained.
