Which Tokens Need Context? A Reference-Based Analysis of Translation Responsibility Using Fertility and Entropy
arXiv:2606.29489v1 Announce Type: new Abstract: When humans translate, not every word depends equally on the surrounding context. Some tokens, particularly function words like pronouns and auxiliaries, rely heavily on preceding or following sentences, while others, such as proper nouns, do not. Understanding this inherent context sensitivity is essential for evaluating whether machine translation systems use context in human-like ways. However, existing approaches to analysing context usage rely on discourse-specific test sets or model internals, making them narrow or model-dependent. We propo
This research is emerging now as the field of machine translation matures and researchers seek more nuanced methods to evaluate and improve AI systems' contextual understanding, an increasingly critical aspect of AI performance.
A strategic reader should care because improving contextual understanding in machine translation directly impacts the utility and reliability of advanced AI systems, especially in high-stakes environments where precise language is critical.
Current methods for evaluating machine translation context usage are often narrow or model-dependent; this research proposes a more universal, reference-based approach, potentially leading to more human-like translation systems.

More sophisticated and human-like machine translation systems will become standard.
Improved translation quality could accelerate global communication and information exchange, reducing language barriers in business and diplomacy.
As AI systems better understand context, their applications beyond translation, such as summarization and content generation, will also become significantly more robust and reliable.
