用跨语言解释习语，帮助学习者理解难懂的表达。
CLIX: Cross-Lingual Explanations of Idiomatic Expressions
- 通过跨语言方式解释习语，降低理解门槛。
- 大模型在习语解释上表现有潜力但仍有挑战。
- 适合语言教育工具开发者参考改进。
自动定义生成系统被提出以支持语言学习者的词汇扩展。然而，这些系统的主要障碍在于学习者常因不熟悉的词汇和语法难以理解定义，尤其是在涉及非标准语言时。为解决此问题，我们提出了跨语言习语解释任务（CLIX）。我们评估了当前NLP模型在此任务上的能力，发现尽管仍具挑战性，大型语言模型展现出一定潜力。最后，我们进行了详细的错误分析，指出了在将此类系统可靠集成到教育工具前需解决的关键问题。
原文摘要 · Abstract (English)
Automated definition generation systems have been proposed to support vocabulary expansion for language learners. The main barrier to the success of these systems is that learners often struggle to understand definitions due to the presence of potentially unfamiliar words and grammar, particularly when non-standard language is involved. To address these challenges, we propose CLIX, the task of Cross-Lingual explanations of Idiomatic eXpressions. We explore the capabilities of current NLP models for this task, and observe that while it remains challenging, large language models show promise. Finally, we perform a detailed error analysis to highlight the key challenges that need to be addressed before we can reliably incorporate these systems into educational tools.
