用电影叙事法讲清楚城市出租车轨迹数据,让复杂时空信息易懂又动人。
Comprehending Spatio-temporal Data via Cinematic Storytelling using Large Language Models
- 用大模型+检索增强生成,把轨迹数据变成有情节的故事
- 通过热力图故事和单次行程叙事,揭示城市出行模式
- 适合想让数据更易懂的科研、政策与公众传播场景
时空数据捕捉空间与时间的复杂动态,但传统可视化复杂难懂,需专业知识,难以打动大众。本文提出MapMuse——一种基于叙事的时空数据解读框架,将数据转化为引人入胜的叙事体验。利用大语言模型,结合检索增强生成(RAG)与代理技术,生成完整故事。借鉴电影叙事原则,强调清晰性、情感共鸣与受众导向设计。以数百万辆出租车行程终点数据为例,呈现两种视角:一是基于热力图的宏观城市出行模式故事;二是追踪一次长途行程的微观叙事,融入地标与时间变化。将地点拟作角色,移动作为剧情,证明数据叙事能激发洞察、提升参与度并推动行动。案例显示MapMuse可弥合数据复杂性与人类理解之间的鸿沟。本文旨在展示电影式叙事作为时空数据传播工具的潜力,并指出未来研究的开放问题与机遇。
原文摘要 · Abstract (English)
Spatio-temporal data captures complex dynamics across both space and time, yet traditional visualizations are complex, require domain expertise and often fail to resonate with broader audiences. Here, we propose MapMuse, a storytelling-based framework for interpreting spatio-temporal datasets, transforming them into compelling, narrative-driven experiences. We utilize large language models and employ retrieval augmented generation (RAG) and agent-based techniques to generate comprehensive stories. Drawing on principles common in cinematic storytelling, we emphasize clarity, emotional connection, and audience-centric design. As a case study, we analyze a dataset of taxi trajectories. Two perspectives are presented: a captivating story based on a heat map that visualizes millions of taxi trip endpoints to uncover urban mobility patterns; and a detailed narrative following a single long taxi journey, enriched with city landmarks and temporal shifts. By portraying locations as characters and movement as plot, we argue that data storytelling drives insight, engagement, and action from spatio-temporal information. The case study illustrates how MapMuse can bridge the gap between data complexity and human understanding. The aim of this short paper is to provide a glimpse to the potential of the cinematic storytelling technique as an effective communication tool for spatio-temporal data, as well as to describe open problems and opportunities for future research.
