Despite this, deception detection research is hindered by the lack of high-quality deception datasets, as well as the difficulties of learning multimodal features effectively. To address this issue, we introduce DOLOS\\footnote {The name ``DOLOS\" comes from Greek mythology.}, the largest gameshow deception detection dataset with rich deceptive conversations.
