## parse_conll()


Build documents from CoNLL content.


Usage

``` python
parse_conll(
    content, *, scheme="bio", repair=False, text=None, comment_prefix=None
)
```


## Parameters


`content: str`  
The file content.

`scheme: Scheme = ``"bio"`  
The tag scheme: `"bio"` (IOB2), `"iob1"`, `"bioes"` or `"bilou"`.

`repair: bool = ``False`  
Accept invalid tag sequences (e.g. `I-X` after `O`) by starting a new entity there, instead of raising.

`text: str | None = None`  
The true raw text, if known. Tokens are aligned onto it (only whitespace may lie between them) and offsets refer to it. Only for content with exactly one document.

`comment_prefix: str | None = None`  
Treat lines starting with this prefix (e.g. `"#"`) as comments. A comment `doc_id = X` or `newdoc id = X` starts a new document with ID `X`; other comments are kept in `metadata["conll_comments"]`. Off by default, since `#` can also be a token.
