自动分析新闻中实体的叙事角色,揭示其是主角、反派还是无辜者。
FRaN-X: FRaming and Narratives-eXplorer
- 两阶段系统:先识别实体,再细粒度分类其叙事角色。
- 支持5种语言、2个领域,可同时分析4篇文章并生成对比图谱。
- 提供搜索、时间线和交互界面,适合媒体分析与舆情研究。
我们提出FRaN-X,一个自动从原始文本中检测实体提及并分类其叙事角色的框架与叙事探索工具。该系统采用两阶段架构,结合序列标注与细粒度角色分类,揭示实体在叙事中是主角、反派或无辜者,并基于22个细分角色构成的独特分类体系实现精准刻画。系统支持俄语、英语、印地语、保加利亚语和葡萄牙语五种语言,覆盖俄乌冲突与气候变化两个领域。用户可通过交互式网页界面,聚焦单篇文章或并行分析最多四篇文本,获取聚合层面的直观图谱,展现一组文章的整体叙事倾向。系统还提供实体检索功能与时间线视图,帮助分析师追踪实体角色在不同语境中的动态变化。所有模型与代码以MIT许可证开放,系统已公开部署于https://fran-x.streamlit.app/,视频演示见https://youtu.be/VZVi-1B6yYk。
原文摘要 · Abstract (English)
We present FRaN-X, a Framing and Narratives Explorer that automatically detects entity mentions and classifies their narrative roles directly from raw text. FRaN-X comprises a two-stage system that combines sequence labeling with fine-grained role classification to reveal how entities are portrayed as protagonists, antagonists, or innocents, using a unique taxonomy of 22 fine-grained roles nested under these three main categories. The system supports five languages (Bulgarian, English, Hindi, Russian, and Portuguese) and two domains (the Russia-Ukraine Conflict and Climate Change). It provides an interactive web interface for media analysts to explore and compare framing across different sources, tackling the challenge of automatically detecting and labeling how entities are framed. Our system allows end users to focus on a single article as well as analyze up to four articles simultaneously. We provide aggregate level analysis including an intuitive graph visualization that highlights the narrative a group of articles are pushing. Our system includes a search feature for users to look up entities of interest, along with a timeline view that allows analysts to track an entity's role transitions across different contexts within the article. The FRaN-X system and the trained models are licensed under an MIT License. FRaN-X is publicly accessible at https://fran-x.streamlit.app/ and a video demonstration is available at https://youtu.be/VZVi-1B6yYk.
