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 c...

Live chats have become a popular form of communication, connecting people all over the globe. We believe that one of the simplest approaches for providing topic information to users joining a chat is keywords. In this paper, we present a method to automatically extract contextually relevant keywords for multi-party live chats. In our work, we identify keywords that are associated with specific ...

This document specifies an application-level protocol (i.e., payload type) for chat tools using the Real Time Protocol for Distributed Interactive Media (RTP/I). RTP/I defines a standardized framing for the transmission of application data and provides protocol mechanisms that are universally needed for the class of distributed interactive media. A chat tool provides an instant messaging servic...

We describe initial work on extensions to word highlighting for multiparticipant chat to aid users in finding messages of interest, especially during times of high traffic in chat rooms. We have annotated a corpus of chat messages from a technical chat domain (Ubuntu’s technical support), indicating whether they are related to Ubuntu’s new desktop environment Unity. We also created an unsupervi...

Cri-du-chat syndrome is a chromosomal abnormality involving a 5p deletion and is characterised by a cat-like cry, mental retardation, microcephaly and abnormal facial features. We report a case of prenatally-diagnosed cri-du-chat syndrome. Although PAPP-A was low at first trimester screening (FTS), the combined risks of trisomies 21, 18 and 13 were low. Amniocentesis was, however, carried out f...

Automatically identifying the various roles (e.g., mentor, player) in multi-party collaborative chat is a challenging task. To better understand the conversational demands of mentors and players, this paper investigates the dynamics and linguistic features of multi-party chat in the context of an online educational game. In this paper we introduce a novel computational linguistics method using ...

This case study explores the use of learning analytics techniques to monitor students’ conceptual development evidenced in time-stamped logs of a CSCL environment that provides chat, shared whiteboard, and wiki features. The study was conducted in a graduate level research methods course, which included online assignments that required students to collaboratively discuss questions related to st...

Conflicting claims have been presented in the literature about on-line management of personal relationships. The current research, carried out in a substantially descriptive design, aimed to consider psychological and social features of a particular electronic environment, the Chat room. One hundred fifty-eight participants filled out an on-line questionnaire set, designed to investigate the pe...

Since the 1990s, two technologies have reshaped how we see and experience the world around us. These technologies are the Internet and mobile communication, especially smartphones. The Internet provides a cheap and convenient way to explore and communicate with distant people. A multitude of services have converged on the smartphone platform, and potentially the most notable is social networkin...

Emerging evidence suggests that the p75 neurotrophin receptor (p75NTR) mediates cell death; however, it is not known whether p75NTR negatively regulates other neuronal phenotypes. We found that mice null for p75NTR displayed highly significant increases in the size of basal forebrain cholinergic neurons, including those that are TrkA-positive. Cholinergic hippocampal target innervation also was...
