Most of the tokenizers are available in two flavors: a full python implementation and a “Fast” implementation based on the Rust library tokenizers. Tokenization and sentence segmentation in Stanza are jointly performed by the TokenizeProcessor. text. Let us understand this concept of word tokenization with the help of an example sentence – “We will win”. The scanner in this module returns comments as tokens as well, making it useful for implementing “pretty-printers”, including colorizers for on-screen displays. Get started.
