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. 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.

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

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"])
