p
    |  When you call #[code nlp] on a text, spaCy first tokenizes the text to
    |  produce a #[code Doc] object. The #[code Doc] is the processed in several
    |  different steps – this is also referred to as the
    |  #[strong processing pipeline]. The pipeline used by our
    |  #[+a("/docs/usage/models") default models] consists of a
    |  vectorizer, a tagger, a parser and an entity recognizer. Each pipeline
    |  component returns the processed #[code Doc], which is then passed on to
    |  the next component.
