AddedToken

class

tokenizers.

AddedToken

(

content

single_word

= False

lstrip

= False

rstrip

= False

normalized

= True

)

Parameters

  • content ( str ) — The content of the token
  • single_word ( bool , defaults to False ) — Defines whether this token should only match single words. If True , this token will never match inside of a word. For example the token ing would match on tokenizing if this option is False , but not if it is True . The notion of ” inside of a word ” is defined by the word boundaries pattern in regular expressions (ie. the token should start and end with word boundaries).
  • lstrip ( bool , defaults to False ) — Defines whether this token should strip all potential whitespaces on its left side. If True , this token will greedily match any whitespace on its left. For example if we try to match the token [MASK] with lstrip=True , in the text "I saw a [MASK]" , we would match on " [MASK]" . (Note the space on the left).
  • rstrip ( bool , defaults to False ) — Defines whether this token should strip all potential whitespaces on its right side. If True , this token will greedily match any whitespace on its right. It works just like lstrip but on the right.
  • normalized ( bool , defaults to True with —meth: ~tokenizers.Tokenizer.add_tokens and False with add_special_tokens() ): Defines whether this token should match against the normalized version of the input text. For example, with the added token "yesterday" , and a normalizer in charge of lowercasing the text, the token could be extract from the input "I saw a lion Yesterday" .

Represents a token that can be be added to a Tokenizer . It can have special options that defines the way it should behave.
