PRIM BLEU measures the degree of lexical overlap between the generated translation and the reference translation based on n-gram precision; a higher value indicates the translation is closer to the reference.

UnverifiedThe core idea of BLEU is to compute n-gram overlap between machine translations and reference translations; its limitations include insensitivity to word order changes, inability to capture semantically equivalent synonym substitutions, and dependence on the quality and quantity of reference translations.76% similarVerifiedBLEU is commonly used for machine translation evaluation, and ROUGE is widely applied to summarization tasks; both measure text quality by statistically calculating n-gram overlap71% similarVerifiedBLEU is a natural language generation evaluation metric proposed in the 1990s that measures quality by calculating the n-gram overlap between generated text and reference translations, and remains the standard benchmark in the field of machine translation.67% similarUnverifiedAutomatic metrics such as BLEU and ROUGE require the existence of a high-quality reference translation, and many real-world scenarios do not have this condition.66% similarUnverifiedSynonym normalization can be achieved by using sentence embedding models such as Sentence-BERT to map words into dense vectors, and then computing semantic proximity via cosine similarity.63% similar
