LIAR

LIAR is a publicly available dataset for fake news detection. A decade-long of 12.8K manually labeled short statements were collected in various contexts from POLITIFACT.COM, which provides detailed analysis report and links to source documents for each case. This dataset can be used for fact-checking research as well. Notably, this new dataset is an order of magnitude larger than previously largest public fake news datasets of similar type. The LIAR dataset4 includes 12.8K human labeled short statements from POLITIFACT.COM’s API, and each statement is evaluated by a POLITIFACT.COM editor for its truthfulness.

LIAR数据集是一款面向假新闻检测任务的公开可用数据集。该数据集历时十年，从POLITIFACT.COM平台采集了12.8千条经人工标注的短文本陈述，涵盖多种语境；POLITIFACT.COM会为每一条陈述提供详细分析报告与源文档链接，且该数据集同样可应用于事实核查相关研究。值得注意的是，其规模较此前同类规模最大的公开假新闻数据集高出一个数量级。LIAR数据集4通过POLITIFACT.COM的应用程序编程接口（Application Programming Interface, API）获取上述数据，每一条陈述的真实性均由该平台的编辑进行评估。
