While liking or upvoting a post on a mobile app is easy to do, replying with a written note is much more difficult, due to both the cognitive load of coming up with a meaningful response as well as the mechanics of entering the text. Here we present a novel textual reply generation model that goes beyond the current auto-reply and predictive text entry models by taking into account the content ...

In natural conversation, the minimal gaps and overlaps of the turns at talk indicate an accurate regulation of the timings of the turn-taking system. Here we studied how the turn-taking affects the gaze of a non-involved viewer of a two-person conversation. The subjects were presented with a video of a conversation while their eye gaze was tracked with an infrared camera. As a control, the vide...

Conversational practices do not occur at a single unit of analysis. To understand the interplay between social positioning, information sharing, and rhetorical strategy in language, various granularities are necessary. In this work we present a machine learning model for multi-party chat which predicts conversation structure across differing units of analysis. First, we mark sentence-level beha...

We study turn-taking behaviour in non-cooperative dialogue for the development of believable characters in a serious game for conversational skill learning in the police interview context. We describe a perception study to see how participants perceive a suspect’s interpersonal stance, rapport, face, and deception when the turn-taking of the subject varies. We influence the perception of the su...

The use of social media creates the opportunity to turn organization-wide knowledge sharing in the workplace from an intermittent, centralized knowledge management process to a continuous online knowledge conversation of strangers, unexpected interpretations and re-uses, and dynamic emergence. We theorize four affordances of social media representing different ways to engage in this publicly vi...

This paper explores the role of gaze in coordinating turn-taking in mixed-initiative conversation and specifically how gaze indicators might be usefully modeled in computational dialogue systems. We analyzed about 20 minutes of videotape of eight dialogues by four pairs of subjects performing a simple face-to-face cooperative laboratory task. We extend previous studies by explicating gaze patte...

Vivas have multiple functions in academia, but their main goal is completing thesis evaluation. At the heart of this evaluation is a series of criticisms and their responsive turns by which participants talk vivas as institution into being (Heritage, 1997). Turn-taking is one of the many ways vivas are talked into being. This study drew upon conversation analysis to look into the turn allocatio...

This study explores how student learning via asynchronous, threaded discussion boards may be managed successful. We examine the elements of course scaffolding on that affect student learning and engagement in discussion. We explore the role of the instructor in mediating learning. We base our findings on an analysis of 21 online courses in the IS domain, conducted by multiple instructors over a...
