Dataset Card for PUBHEALTH

Dataset Summary

PUBHEALTH is a comprehensive dataset for explainable automated fact-checking of public health claims. Each instance in the PUBHEALTH dataset has an associated veracity label (true, false, unproven, mixture). Furthermore each instance in the dataset has an explanation text field. The explanation is a justification for which the claim has been assigned a particular veracity label.

Dataset Structure

Data Instances

The following is an example instance of the PUBHEALTH dataset:

Field	Example
claim	Expired boxes of cake and pancake mix are dangerously toxic.
explanation	What's True: Pancake and cake mixes that contain mold can cause life-threatening allergic reactions. What's False: Pancake and cake mixes that have passed their expiration dates are not inherently dangerous to ordinarily healthy people, and the yeast in packaged baking products does not "over time develops spores."
label	mixture
author(s)	David Mikkelson
date published	April 19, 2006
tags	food, allergies, baking, cake
main_text	In April 2006, the experience of a 14-year-old who had eaten pancakes made from a mix that had gone moldy was described in the popular newspaper column Dear Abby. The account has since been circulated widely on the Internet as scores of concerned homemakers ponder the safety of the pancake and other baking mixes lurking in their larders [...]

Dataset Creation

Curation Rationale

The dataset was created to explore fact-checking of difficult to verify claims i.e., those which require expertise from outside of the journalistics domain, in this case biomedical and public health expertise.

It was also created in response to the lack of fact-checking datasets which provide gold standard natural language explanations for verdicts/labels.

Source Data

Initial Data Collection and Normalization

The dataset was retrieved from the following fact-checking, news reviews and news websites:

URL	Type
http://snopes.com/	fact-checking
http://politifact.com/	fact-checking
