CFEVER: A Chinese Fact Extraction and VERification Dataset
This provides a new dataset for developing automated fact-checking systems in Chinese, addressing the problem of misinformation for Chinese speakers, but it is incremental as it adapts an existing English dataset.
The authors introduced CFEVER, a Chinese dataset with 30,012 manually created claims for fact extraction and verification, achieving a Fleiss' kappa inter-annotator agreement of 0.7934. They demonstrated it as a rigorous benchmark by testing state-of-the-art approaches and a simple baseline.
We present CFEVER, a Chinese dataset designed for Fact Extraction and VERification. CFEVER comprises 30,012 manually created claims based on content in Chinese Wikipedia. Each claim in CFEVER is labeled as "Supports", "Refutes", or "Not Enough Info" to depict its degree of factualness. Similar to the FEVER dataset, claims in the "Supports" and "Refutes" categories are also annotated with corresponding evidence sentences sourced from single or multiple pages in Chinese Wikipedia. Our labeled dataset holds a Fleiss' kappa value of 0.7934 for five-way inter-annotator agreement. In addition, through the experiments with the state-of-the-art approaches developed on the FEVER dataset and a simple baseline for CFEVER, we demonstrate that our dataset is a new rigorous benchmark for factual extraction and verification, which can be further used for developing automated systems to alleviate human fact-checking efforts.
