# SARA QASPER (reformatted)

Reformatted [QASPER](https://huggingface.co/datasets/allenai/qasper) data used by
**SARA: Selective and Adaptive Retrieval-augmented Generation with Context Compression** (ACL 2026,
[arXiv:2507.05633](https://arxiv.org/abs/2507.05633)). Code: [Ahren09/SARA](https://github.com/Ahren09/SARA).

The SARA Quick Start (`python -m src.data.make_qasper_splits`) downloads this dataset automatically;
you can also load it directly:

```python
from datasets import load_dataset

qa = load_dataset("Ahren09/SARA-QASPER", "qa")                          # train / test
align = load_dataset("Ahren09/SARA-QASPER", "compression_alignment")    # train / validation
```

## Configs

### `qa` (default)

One record per answerable QASPER question. `train` (2,321 rows over the official
train papers) and `test` (1,312 rows, official test papers).

| Field | Type | Description |
| :--- | :--- | :--- |
| `id` | str | Running row index. |
| `example_id` | str | Paper index — used for leakage-safe document-level train/dev splitting. |
| `question` | str | The QASPER question. |
| `context` | list[str] | BM25-ranked paper contexts, each formatted `"Section name\t<text>"`. Retrieval in SARA is built in-memory from this field; no separate index is needed. |
| `answer` | str | Short gold answer (a span, value, phrase, or yes/no) derived from the official QASPER annotations. Used as both the training target and the evaluation reference. |
| `choices` | null | Unused for QASPER (kept for schema compatibility with multiple-choice datasets). |
| `question_type` | str | One of `extractive`, `free_form`, `yes_no`, `unanswerable`. |

Models trained on this data answer with chain-of-thought followed by the final short answer wrapped
in tags: `... reasoning ... <answer>short answer</answer>`; evaluation extracts the tagged span and
scores it against `answer`.

### `compression_alignment`

Text snippets from QASPER paper bodies used for the SARA projector-alignment warm-up (the projector
learns to reconstruct a document from its semantic compression vector before QA fine-tuning).
`train` (22,111 rows) and `validation` (200 rows); each record is `{"text": "<document text snippet>"}`.

## Provenance

- Derived from [`allenai/qasper`](https://huggingface.co/datasets/allenai/qasper)
  (Dasigi et al., NAACL 2021), released under **CC BY 4.0**. This derivative is released under the
  same license with attribution.
- `context` was built from each paper's title/abstract/sections and BM25-ranked per question;
  `BIBREF` citation markers were stripped.
- Earlier revisions of this dataset carried an additional LLM-rewritten `answer_reformatted` field;
  it has been removed — the short gold `answer` is the single reference. The old revision remains
  available in this repo's git history.
