Dataset Card for "CsFEVERv2"

Dataset Description

CsFEVERv2 is a dataset for Czech fact-checking developed as part of a bachelor thesis at the Artificial Intelligence Center of the Faculty of Electrical Engineering of the Czech technical university in Prague. The dataset consists of an original subset, which is only an iteration of CsFEVER with new data and better processing and f1, precision, and 07 subsets filtered using an NLI model and optimized threshold values. The subset wiki_pages is a processed Wikipedia dump from August 2022 with correct revids. This subset should be used to map evidence from datasets to Wikipedia texts. Additionaly preprocessed datasets original_nli, f1_nli, precision_nli, 07_nli, for training of NLI models are included.

The original subset can be used to generate other filtered datasets by filtering with other thresholds using predicted_label and predicted_score fields.

Dataset Usage Example

from datasets import load_dataset

#load default (original) subset
dataset = load_dataset("ctu-aic/csfever_v2")
dataset = load_dataset("ctu-aic/csfever_v2", "original")

#load f1, f1_nli, precision, precision_nli, 07, and 07_nli subsets
dataset = load_dataset("ctu-aic/csfever_v2", "f1")

#load wiki_pages subset
dataset = load_dataset("ctu-aic/csfever_v2", "wiki_pages")
