Character N-gram F-score, o ChrF, es una métrica de evaluación para traducción automática y generación de texto. Mide la superposición entre n-gramas a nivel de caracteres en el texto generado y el texto de referencia, lo que la hace útil para lenguas y tareas en las que la tokenización a nivel de palabra es menos fiable.
A metric to evaluate machine translation models. Character N-gram F-score determines the degree to which N-grams in reference text overlap the N-grams in an ML model's generated text. Character N-gram F-score is similar to metrics in the ROUGE and BLEU families, except that: - Character N-gram F-score operates on character N-grams. - ROUGE and BLEU operate on word N-grams or tokens.
