O QUE ESTA CAPACIDADE SIGNIFICA

Takes source-language text and outputs a translation. Unlike open-ended generation it has an objective reference — whether the translation is faithful — and unlike summarisation it should not drop content but rebuild it as evenly as possible. Beyond prose it must handle terminology lists, markup and placeholders so the output can be pasted back into the original system.

Como é feita tecnicamente

When the Transformer was introduced in 2017, the encoder–decoder with attention was designed for translation, and neural machine translation has since largely replaced statistical systems. Source sentences are encoded and target sentences decoded, trained on parallel corpora. Recent multilingual models cover a hundred-plus languages with one set of parameters and treat translation as an instruction, while low-resource languages lean on transfer from high-resource ones and back-translation.

Como avaliar se funciona bem

BLEU
N-gram overlap with references; higher is better but not readability
COMET
A neural faithfulness score for translations
chrF
Character-level F-score, steadier for morphologically rich languages

Limites e dificuldades

  • Quality on low-resource languages and dialects trails high-resource ones by a wide margin
  • Terminology and proper-noun consistency drifts across a long document
  • Idioms, puns and culture-specific wording are often translated literally and lose meaning
