|
|
A group of arbitrary, potentially overlapping [`Span`](/api/span) objects that
|
|
all belong to the same [`Doc`](/api/doc) object. The group can be named, and you
|
|
can attach additional attributes to it. Span groups are generally accessed via
|
|
the [`Doc.spans`](/api/doc#spans) attribute, which will convert lists of spans
|
|
into a `SpanGroup` object for you automatically on assignment. `SpanGroup`
|
|
objects behave similar to `list`s, so you can append `Span` objects to them or
|
|
access a member at a given index.
|
|
|
|
## SpanGroup.\_\_init\_\_ {#init tag="method"}
|
|
|
|
Create a `SpanGroup`.
|
|
|
|
> #### Example
|
|
>
|
|
> ```python
|
|
> doc = nlp("Their goi ng home")
|
|
> spans = [doc[0:1], doc[2:4]]
|
|
>
|
|
> # Construction 1
|
|
> from spacy.tokens import SpanGroup
|
|
>
|
|
> group = SpanGroup(doc, name="errors", spans=spans, attrs={"annotator": "matt"})
|
|
> doc.spans["errors"] = group
|
|
>
|
|
> # Construction 2
|
|
> doc.spans["errors"] = spans
|
|
> assert isinstance(doc.spans["errors"], SpanGroup)
|
|
> ```
