p A container for accessing linguistic annotations.

p
    |  A #[code Doc] is a sequence of #[+api("token") #[code Token]] objects.
    |  Access sentences and named entities, export annotations to numpy arrays,
    |  losslessly serialize to compressed binary strings. The #[code Doc] object
    |  holds an array of #[code TokenC] structs. The Python-level #[code Token]
    |  and #[+api("span") #[code Span]] objects are views of this array, i.e.
    |  they don't own the data themselves.

+aside-code("Example").
    # Construction 1
    doc = nlp(u'Some text')

    # Construction 2
    from spacy.tokens import Doc
    doc = Doc(nlp.vocab, words=[u'hello', u'world', u'!'],
                               spaces=[True, False, False])

+h(2, "init") Doc.__init__
    +tag method

p
    |  Construct a #[code Doc] object. The most common way to get a #[code Doc]
    |  object is via the #[code nlp] object.

        +cell #[code vocab]
        +cell #[code Vocab]
        +cell A storage container for lexical types.

    +row
        +cell #[code words]
        +cell -
        +cell A list of strings to add to the container.

    +row

        +cell -
        +cell
            |  A list of boolean values indicating whether each word has a
            |  subsequent space. Must have the same length as #[code words], if
            |  specified. Defaults to a sequence of #[code True].

    +footrow
        +cell returns
        +cell #[code Doc]
        +cell The newly constructed object.

+h(2, "getitem") Doc.__getitem__
    +tag method

p
    |  Get a #[+api("token") #[code Token]] object at position #[code i], where
    |  #[code i] is an integer. Negative indexing is supported, and follows the
    |  usual Python semantics, i.e. #[code doc[-2]] is #[code doc[len(doc) - 2]].

+aside-code("Example").
    doc = nlp(u'Give it back! He pleaded.')

p
    |  Get a #[+api("span") #[code Span]] object, starting at position
    |  #[code start] (token index) and ending at position #[code end] (token
    |  index).

p
    |  For instance, #[code doc[2:5]] produces a span consisting of tokens 2, 3
    |  and 4. Stepped slices (e.g. #[code doc[start : end : step]]) are not
    |  supported, as #[code Span] objects must be contiguous (cannot have gaps).
    |  You can use negative indices and open-ended ranges, which have their
    |  normal Python semantics.

    |  faster-than-Python speeds are required, you can instead access the

    |  from Cython.

p A container for accessing linguistic annotations.

    |  A #[code Doc] is a sequence of #[+api("token") #[code Token]] objects.
    |  Access sentences and named entities, export annotations to numpy arrays,
    |  losslessly serialize to compressed binary strings. The #[code Doc] object
    |  holds an array of #[code TokenC] structs. The Python-level #[code Token]
    |  and #[+api("span") #[code Span]] objects are views of this array, i.e.
    |  they don't own the data themselves.

+aside-code("Example").

+h(2, "init") Doc.__init__
    +tag method

p
    |  Construct a #[code Doc] object. The most common way to get a #[code Doc]
    |  object is via the #[code nlp] object.

p
    |  Get a #[+api("token") #[code Token]] object at position #[code i], where

    |  index).

p
    |  For instance, #[code doc[2:5]] produces a span consisting of tokens 2, 3
    |  and 4. Stepped slices (e.g. #[code doc[start : end : step]]) are not
    |  supported, as #[code Span] objects must be contiguous (cannot have gaps).
