CLIMATE-FEVER is a dataset adopting the FEVER methodology that consists of 1,535 real-world claims regarding climate-change. Each claim is accompanied by five manually annotated evidence sentences retrieved from Wikipedia that support, refute or do not give enough information to validate the claim. The total dataset thus contains 7,675 claim-evidence pairs. Furthermore, the dataset features challenging claims that relate multiple facets and disputed cases of claims where both supporting and refuting evidence are present.
The dataset is based on a paper CLIMATE-FEVER: A Dataset for Verification of Real-World Climate Claims by Thosas Diggelmann, Jordan Boyd-Graber, Jannis Bulian, Massimiliano Ciaramita,and Markus Leippold. The paper was accepted for the Tackling Climate Change with Machine Learning workshop at NeurIPS 2020. The workshop was held online in December 2020.
