# DDI Corpus Processed

Drug-Drug Interaction (DDI) detection dataset processed from the [SemEval-2013 DDI Corpus](https://github.com/isegura/DDICorpus).

## Dataset Description

This dataset contains drug-drug interaction examples for 5-class classification:

- **MECHANISM**: Mechanistic description of how drugs interact (e.g., inhibition, induction)
- **EFFECT**: Clinical effect of concurrent use (e.g., increased toxicity, decreased efficacy)
- **ADVISE**: Advisory or cautionary information about concurrent use
- **INT**: General interaction without specific type
- **NONE**: No interaction between the drug pair

## Dataset Statistics

| Split | Total | MECHANISM | EFFECT | ADVISE | INT | NONE |
|-------|-------|-----------|--------|--------|-----|------|
| Train | 5,744 | 1,319 (23%) | 1,687 (29%) | 826 (14%) | 189 (3%) | 1,723 (30%) |
| Test | 1,398 | 302 (22%) | 360 (26%) | 221 (16%) | 96 (7%) | 419 (30%) |

## Data Format

Each example contains:
- `sentence`: The original sentence containing drug mentions
- `drug1`: First drug entity
- `drug2`: Second drug entity
- `relation`: Interaction type (MECHANISM, EFFECT, ADVISE, INT, or NONE)
- `source_file`: Original XML source file
- `sentence_id`: Original sentence ID
- `pair_id`: Original pair ID

## Usage

```python
from datasets import load_dataset

dataset = load_dataset("MaziyarPanahi/DDI-Corpus-Processed")
```
