# BioASQ - All Question Types

A comprehensive collection of BioASQ challenge questions organized by question type as separate splits.

## Purpose

This dataset is a **convenience collection** of BioASQ questions reformatted for easier use. The original source data is from the [BioASQ Challenge](http://bioasq.org/). We created this reorganized version (with question types as splits) to facilitate evaluation in our PaperSearchQA work.

**IMPORTANT**: This is not the original BioASQ dataset. We have simply reorganized the BioASQ data into splits by question type. All underlying question and answer data is from BioASQ.

## Dataset Description

This dataset contains **5,404 biomedical questions** from the BioASQ challenge, distributed across four question types:

- **factoid** (1,609 samples): Questions with short factual answers
- **yesno** (1,464 samples): Yes/No questions
- **summary** (1,283 samples): Questions requiring summarization
- **list** (1,048 samples): Questions with list-based answers

Each question type is provided as a separate split for convenient filtering and evaluation.

## Source and Attribution

**Original Data Source**: [BioASQ Challenge](http://bioasq.org/)

BioASQ is a series of challenges on large-scale biomedical semantic indexing and question answering.

**IMPORTANT**: To use BioASQ data, you must:
1. Register at: https://bioasq.org/
2. Review and comply with BioASQ terms of use
3. Cite the BioASQ papers (see below)
4. Acknowledge the BioASQ dataset in any publications

## Dataset Structure

### Data Fields

Each sample contains:

- `id`: Unique question identifier
- `body`: The question text
- `type`: Question type (factoid, yesno, summary, or list)
- `ideal_answer`: Reference answer(s)
- `exact_answer`: Structured answer (for factoid/list questions)
- `documents`: URLs of relevant PubMed documents
- `snippets`: Relevant text snippets from the documents

### Data Splits

The dataset is organized into 4 splits by question type:

| Split | Examples |
|-------|----------|
| factoid | 1,609 |
| yesno | 1,464 |
| summary | 1,283 |
| list | 1,048 |
| **Total** | **5,404** |

## Usage

```python
from datasets import load_dataset

# Load all question types
dataset = load_dataset("jmhb/BioASQ")

# Load only factoid questions
factoid = load_dataset("jmhb/BioASQ", split="factoid")

# Load specific question types
dataset = load_dataset("jmhb/BioASQ", split=["factoid", "yesno"])
```
