同一教训，不同故事：大型语言模型中文化叙事的跨语言重构
Same Lesson, Different Story: Cross-Lingual Reconstruction of Cultural Narratives in Large Language Models
AI总结：
本研究通过跨语言谚语集和四种LLM生成叙事，评估模型在跨语言条件下是否保留文化意义，发现跨语言提示基本保留语义但改变叙事结构，且模型间存在强收敛。
摘要：
当多种文化传达相同的道德教训时，文化根基背景的评估变得复杂。这一挑战与大型语言模型（LLMs）尤为相关，因为它们跨多种语言和文化背景生成叙事。然而，当等效的道德教训通过不同的文化形式传达时，这些模型是否保留文化根基意义仍不确定。本研究引入了一个多语言评估叙事框架，该框架整合了涵盖15种语言的414条谚语的跨语言集合，并使用四种LLM生成了13k个叙事。通过使用语义等效的谚语作为文化根基提示，分析评估了模型是否跨语言保留意义、跨语言条件如何影响叙事实现，以及不同模型家族是否收敛于相似的解释。结果表明，跨语言提示在很大程度上保留了谚语级别的语义意义，同时系统性地重新分配了主体性、社会定位和叙事结构。此外，在单语和跨语言设置中都观察到了强烈的模型间收敛，这表明多语言LLM依赖于共享的语义抽象，尽管存在架构和语言差异。这些发现揭示了需要对文化根基进行更全面评估。在多语言叙事评估中仅依赖语义相似性可能会高估文化保留，因为它忽略了叙事表达中具有文化意义的变异。
英文摘要：
The evaluation of cultural grounding context becomes complex when multiple cultures convey the same moral lesson. This challenge is particularly relevant to large language models (LLMs), which produce narratives across a wide range of languages and cultural contexts. However, it remains uncertain whether these models preserve culturally grounded meaning when equivalent moral lessons are conveyed through distinct cultural forms. This study introduces a multilingual evaluation narrative framework that integrates a cross-linguistic collection of 414 proverbs spanning 15 languages and uses four LLMs to generate 13k narratives. By employing semantically equivalent proverbs as culturally grounded prompts, the analysis assesses whether models preserve meaning across languages, how cross-lingual conditioning influences narrative realization, and whether different model families converge on similar interpretations. Results indicate that cross-lingual prompting largely preserves proverb-level semantic meaning while systematically redistributing agency, social positioning, and narrative structure. Additionally, strong inter-model convergence is observed in both monolingual and cross-lingual settings, suggesting that multilingual LLMs rely on shared semantic abstractions despite architectural and linguistic differences. These findings shed light on the need for more comprehensive evaluations of cultural grounding. Relying exclusively on semantic similarity in multilingual narrative assessments may overestimate cultural preservation by neglecting culturally meaningful variations in narrative expression.
