"Liar, Liar Pants on Fire": A New Benchmark Dataset for Fake News Detection
This provides a larger benchmark dataset for researchers in fake news detection, though it is incremental in scale.
The authors tackled the lack of labeled benchmark datasets for fake news detection by creating liar, a new publicly available dataset with 12.8K manually labeled statements, which is an order of magnitude larger than previous datasets, and they showed that a hybrid convolutional neural network integrating meta-data with text improves a text-only model.
Automatic fake news detection is a challenging problem in deception detection, and it has tremendous real-world political and social impacts. However, statistical approaches to combating fake news has been dramatically limited by the lack of labeled benchmark datasets. In this paper, we present liar: a new, publicly available dataset for fake news detection. We collected a decade-long, 12.8K manually labeled short statements 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. Empirically, we investigate automatic fake news detection based on surface-level linguistic patterns. We have designed a novel, hybrid convolutional neural network to integrate meta-data with text. We show that this hybrid approach can improve a text-only deep learning model.
