Exemple

  • BLEU calculates the number of matches for each n-gram based on the maximum number of times the n-gram occurs in common with any one of the references. (Sai, Mohankumar, Arora & Khapra, 2020)
  • If the n-gram is a term the input is labelled as positive training example. (Rigouts Terryn, Hoste, Drouin & Lefever, 2020)
  • Ngrams are annotated with part-of-speech tags (e.g. in the phrase he burnt the toast burnt is a verb; in the burnt toast burnt is an adjective) and head-modifier dependencies (e.g. in the phrase the little black book little modifies book). (Lin, Michel, Aiden Lieberman, Orwant, Brockman & Petrov, 2012)
