# Cochrane Screening SFT
Supervised fine-tuning (SFT) chat dataset for **Cochrane-style title and abstract screening**.
Each example is a chat conversation that asks a model to predict a screening decision
(`include` / `exclude` / `uncertain`) and a short justification (`reason`).
Code: [ljwa2323/cochrane-screening-slm](https://github.com/ljwa2323/cochrane-screening-slm)
## Dataset summary
| Split / config | Records | Role |
| --- | ---: | --- |
| `train` | 416,799 | LoRA SFT training |
| `validation` | 46,311 | Training-time validation (10% stratified holdout from development data) |
| `test` | 26,673 | Internal held-out test split |
| `heldout_reviews1` | 26,858 | External reviews (random Cochrane set) |
| `heldout_reviews2` | 4,391 | External reviews (HIV-focused set) |
| `heldout_reviews3` | 19,007 | External reviews (heart/CVD-focused set) |
Label mapping used when building the dataset:
- `0.0` -> `exclude`
- `0.5` -> `uncertain`
- `1.0` -> `include`
Approximate label counts on the development-derived set (train+val source):
- exclude: 221,129
- uncertain: 160,861
- include: 81,120
## Data fields
Each `*.jsonl` line contains:
| Field | Type | Description |
| --- | --- | --- |
| `messages` | list | Chat turns: `system`, `user`, `assistant` |
| `row_id` | int | Source row id |
| `label` | string | Gold label: `include` / `exclude` / `uncertain` |
The assistant target is a JSON object:
```json
{"label": "include|exclude|uncertain", "reason": "<brief explanation>"}
```
## How to load
```python
from datasets import load_dataset
# Internal splits
ds = load_dataset("deepcoder2024/cochrane-screening-sft")
print(ds)
# External held-out reviews
hr1 = load_dataset("deepcoder2024/cochrane-screening-sft", "heldout_reviews1")
hr2 = load_dataset("deepcoder2024/cochrane-screening-sft", "heldout_reviews2")
hr3 = load_dataset("deepcoder2024/cochrane-screening-sft", "heldout_reviews3")
```
> Tip: ignore `*_manifest.json` files when loading. They are metadata only and should not be parsed as chat examples.
## Intended use
- Fine-tune small language models (e.g., Qwen3 LoRA) for title/abstract screening
- Evaluate screening label + reason generation on internal and external review sets
## Out-of-scope use
- Not a substitute for expert systematic-review judgment
- Not intended for clinical decision-making about individual patients
- Labels and reasons are for research / screening-assistance experiments only
