چکیده
This paper describes a new experimental system, the Automated Deception Analysis Machine (ADAM), that was used to conduct automated, chat-based interviews and perform deception detection of the text-based responses. 108 participants were interviewed by this new chatbot agent and they provided 3,162 chat-based responses. Several new metrics were discovered that highly correlate to deceit. ADAM captured extremely accurate response time measurements, clandestinely monitored the number of times the message was edited, and used linguistic features like lexical diversity and word count to analyze the replies. Response time, number of edits, and lexical diversity all were highly correlated to deceptive responses. The paper also describes several classification algorithms that were implemented by the system to discriminate between truthful and deceitful responses. The algorithms achieved a classification of over 90% in some instances for individual questions.

In this paper, we investigate how degree of, and temporal changes in, interactional synchrony can signal whether an interactant is truthful or deceptive. We propose an automated, data-driven and unobtrusive framework using visual cues. Our framework consists of face tracking, gesture detection, facial expression recognition and interactional synchrony estimation. This framework is able to autom...

متن کاملTrust and Deception in Mediated Communication
Guided by interpersonal deception theory and the principle of interactivity, this investigation examined whether communication modalities differentially affect the extent to which group members develop trust or are vulnerable to manipulation and deceit, based on the degree of interactivity the modalities afford. According to the principle of interactivity, involvement and mutuality should incre...
