A new research paper explores the self-referential evaluation loops that can occur when knowledge bases are used as a proxy for gold standards in entity-level machine translation, particularly in low-resource historical domains. The study found that a significant portion of translations, especially for person names, were influenced by the knowledge base injected into the system, rather than being independently assessed. This overlap artificially inflates translation quality scores, masking true model performance and suggesting that the reported gains from knowledge base injection are often a complement to prior performance rather than a genuine improvement in translation capability.
