Researchers Present DOLFIN, a New Test Set for AI Translation for Financial Content

On February 5, 2025, a team of researchers from Grenoble Alpes University and Lingua Custodia , a France-based company specializing in AI and natural language processing (NLP) for the finance sector, introduced DOLFIN, a new test set designed to evaluate document-level machine translation (MT) in the financial domain . The researchers say that the financial domain presents unique challenges for MT due to its reliance on precise terminology and strict formatting rules. They describe it as “an interesting use-case for MT” since key terms often shift meaning depending on context. For example, the French word couverture means blanket in a general setting but hedge in financial texts. Such nuances are difficult to capture without larger translation units. Despite strong research interest in document-level MT, specialized test sets remain scarce, the researchers note. Most datasets focus on general topics rather...
