## Dataset Card for CNER dataset

## Dataset Description

- **Summary:** Concept and Named Entity Recognition (CNER) is a novel task that jointly handles the indentification and classification of concepts and named entities.

## Dataset Structure

The data fields are the same among all splits.
- `tokens`: a `list` of `string` features.
- `pos`: a `list` of `string` features (Part-of-Speech tags). 
- `c_vs_ne`: a `list` of `string` features identifying whether a token is a concept or a named entity.
- `cner_tags`: a `list` of cner classification labels (`str`).
- `cner_tags_ids`: a `list` of cner classification labels ids (`int`). Full tagset with indices:
