This class manages annotations for tagging, dependency parsing and NER.

## GoldCorpus.\_\_init\_\_ {#init tag="method"}

Create a `GoldCorpus`. IF the input data is an iterable, each item should be a
`(text, paragraphs)` tuple, where each paragraph is a tuple
`(sentences, brackets)`, and each sentence is a tuple
`(ids, words, tags, heads, ner)`. See the implementation of
[`gold.read_json_file`](https://github.com/explosion/spaCy/tree/v2.x/spacy/gold.pyx)
for further details.
