A comparison of features for automatic deception detection in synchronous computer-mediated communication This research aims to compare the performance of automatic deception detection in synchronous computermediated communication (CMC) with and without incorporating structural features. In addition, the development of deception detection models draws on the linguistic features that have been widely studied in the online deception literature. The results suggest that structural features can be effective in detecting deception and combining the structural features with linguistic features can improve the performance of detecting deception.
