+# 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
+
