Claire Cardie is co-PI on an NSF grant, "The Dynamics of Digital Deception in Computer Mediated Environments", together with PI Jeff Hancock (assistant professor, communications) and co-PI Mats Rooth (professor, linguistics).

In a Cornell Chronicle article, Hancock says that "By using their [Cardie and Rooth's] expertise in natural language processing and computational linguistics, we will see if we can determine if the very language of deceptive messages is different from that in messages which are not deceptive," said Hancock. "We should have ample opportunity to look at lies because usually people tell one to two lies a day, and these lies range from the trivial to the very serious, including deception between friends and family, in the workplace, and in security and intelligence contexts."
