Evaluating In-Context Translation with Synchronous Context-Free Grammar Transduction
Researchers evaluated how well large language models can perform formal grammar-based translation tasks using in-context learning, finding that LLM translation accuracy degrades significantly with grammar complexity and sentence length. The study identifies specific failure modes including vocabulary hallucination and untranslated source words, revealing fundamental limitations in LLMs' ability to apply formal grammatical rules to translation tasks.
