Lie-M

Lie-M is a real time instant messaging (IM) client based off the open-source Gaim project. Lie-M asks users to classify their messages before they send them to their intended recipients. If the message is deceptive, the user is asked to rate how deceptive it is on a scale from 1-5 (slight to very deceptive) using a small group of radio buttons built into the IM window. The message and its deceptive rating are sent to our server for analysis. The messages of the conversation partner are not sent to our server, nor is the deceptive rating sent to this person. The message, as the research team sees it, is devoid of personally identifying information (such as screen names). Lie-M is used to collect self-reported measures of deception on a massive (500,000-1,000,000 messages) scale. The resulting corpus, the Lie-brary, will be used to study linguistic and temporal correlates of deception. Lie-M is led by Prof. Jeff Hancock.
