Detecting Deception in Civil and Criminal Narratives
Start Date: 5/11/2013Start Time: 11:00 AM
End Date: 5/11/2013End Time: 12:00 PM

Event Description
The International Linguistic Association and the Department of English will host a discussion with Eileen Fitzpatrick of Montclair State University. The talk will consider the reliability of using linguistic cues to identify deceptive and non-deceptive regions in “real world” narratives — criminal statements, police interrogations and legal testimony. To test the accuracy of these cues in predicting deception, we tagged the narratives for 12 language-based deception cues as well as for the truth value of all propositions that could be externally verified as true or false. A measure of the density of cues was then calculated, with high cue density taken to identify a passage as deceptive. This method was 74.9% accurate in predicting True/False on the externally verified propositions, as compared to the baselines that range from 50-57%. This preliminary result suggests that linguistic cues can provide a reasonable guide to the sectioning of narratives into deceptive and non-deceptive statements.
