# SiMoNERo

Romanian biomedical Named Entity Recognition dataset, converted to HuggingFace format.

Entity types: **ANAT** (body parts), **CHEM** (chemicals & drugs), **DISO** (disorders), **PROC** (procedures).

## Splits

| Split | Sentences |
|-------|-----------|
| train | 3,747 |
| validation | 443 |
| test | 491 |

## NER Tags

| ID | Tag |
|----|-----|
| 0 | `O` |
| 1 | `B-ANAT` |
| 2 | `B-CHEM` |
| 3 | `B-DISO` |
| 4 | `B-PROC` |
| 5 | `I-ANAT` |
| 6 | `I-CHEM` |

| 8 | `I-PROC` |

## Usage

```python
from datasets import load_dataset

ds = load_dataset("xd-br0/SiMoNERo")

print(ds["train"][0])
print(ds["train"].features["ner_tags"].feature.names)
# ['O', 'B-ANAT', 'B-CHEM', 'B-DISO', 'B-PROC', 'I-ANAT', 'I-CHEM', 'I-DISO', 'I-PROC']
```
