# QASPER RAG
Dataset for Retrieval-Augmented Generation (RAG) based on [QASPER](https://huggingface.co/datasets/allenai/qasper).
## Structure
| Subset | Splits | Description |
|--------|--------|-------------|
| `corpus` | train (default) | Paper chunks (abstract + full-text paragraphs) shared across all query splits |
| `queries` | train, dev, test | Information-seeking questions over scientific papers |
| `qrels` | train, dev, test | Relevance judgments (query ↔ paragraph chunk) |
| `answers` | train, dev, test | Reference answers (longest valid free-form answer) |
| `top_ranked` | train, dev, test | Paper-scoped candidate pool (all chunks of the query paper) |
| `retrieved_docs` | train, dev, test | Top-k retrieval results with relevance labels |
## Dataset statistics
| Split | Queries | Corpus |
|-------|--------:|-------:|
| train | 2101 | 81550 |
| dev | 890 | 81550 |
| test | 1310 | 81550 |
The corpus is shared across all splits and contains paragraph-level chunks from the abstract and full text of each paper.
- **Dev split:** mapped from the original `validation` split
- **Corpus source:** unique papers from train, validation and test splits
- **Chunking:** one chunk for the abstract (`section_name: abstract`) and one chunk per paragraph in `full_text`
## Source
| Component | QASPER resource |
|-----------|-----------------|
| Train | `train` split from [allenai/qasper](https://huggingface.co/datasets/allenai/qasper) |
| Dev | `validation` split |
| Test | `test` split |
| Corpus | `abstract` + `full_text.paragraphs` |
| Queries | `qas.question` |
| Qrels | `qas.answers[*].answer[*].evidence` matched to corpus chunks |
| Top ranked | All paragraph chunks from the query paper (paper-scoped retrieval pool) |
| Answers | Longest valid answer per question (`free_form_answer`, joined `extractive_spans`, or `Yes`/`No`) |
## Filtering
Questions are kept only when at least one answer satisfies all of the following:
- `unanswerable` is `false`
- the answer has `free_form_answer`, non-empty `extractive_spans`, or `yes_no`
- after removing evidence items containing `FLOAT SELECTED`, at least one answer still has evidence that matches the corpus
Evidence items containing `FLOAT SELECTED` are removed individually. Questions are omitted only when no valid answer has remaining evidence.
## Schema
### corpus
```json
{"id": "...", "title": "...", "section_name": "...", "text": "..."}
```
### queries
```json
{"id": "...", "text": "..."}
```
### qrels
```json
{"query_id": "...", "corpus_id": "...", "score": 1}
```
### answers
```json
{"query_id": "...", "answer": "..."}
```
### top_ranked
```json
{"query-id": "...", "corpus-ids": ["paper_00000", "paper_00001"]}
```
### retrieved_docs
```json
{"query_id": "...", "corpus_id": "...", "rank": 1, "retrieval_score": 0.92, "is_relevant": true}
```
Top-k documents retrieved from the indexed corpus (`is_relevant` is derived from `qrels`).
## Usage
```python
from datasets import load_dataset
corpus = load_dataset("DinoStackAI/qasper-rag", "corpus")["train"]
queries = load_dataset("DinoStackAI/qasper-rag", "queries")
qrels = load_dataset("DinoStackAI/qasper-rag", "qrels")
answers = load_dataset("DinoStackAI/qasper-rag", "answers")
train_queries = queries["train"]
dev_qrels = qrels["dev"]
test_answers = answers["test"]
```
