BLEU stands for Bilingual evaluation understudy, an artificial intelligence abbreviation.
An automatic metric for machine translation that scores how many words and short phrases in a system's output match one or more human reference translations, reported from 0 to 100 or 0 to 1.
Example: The new model improved BLEU by two points on the German-English test set.
Usage notes
Introduced by Kishore Papineni and colleagues at IBM in 2002. BLEU ignores meaning and synonyms, so it correlates only roughly with human judgment, and newer metrics such as COMET and BERTScore use neural models instead. Pronounced "blue".
