This paper presents and discusses the idea that one reason for the success of collaborative problem solving is the polyphonic character of work in small groups. Polyphony, a concept taken from music, may occur in chats for problem solving, transforming dialog into a “thinking device”: Different voices jointly construct a melody (story, or solution) and other voices adopt differential positions,...

We applied a discourse analysis (DA) to the electronic chat room discussions of a 16-week, Internet-based section of a class in statistical methods in psychology. This analysis revealed that across the semester, several DA categories (e.g., total number of student comments) were correlated with final grade in the class. An additional analysis involving only the chat room discussion of Week 3 re...

ESports tournaments, such as Dota 2’s The International (TI), attract millions of spectators to watch broadcasts on online streaming platforms, to communicate, and to share their experience and emotions. Unlike traditional streams, tournament broadcasts lack a streamer figure to which spectators can appeal directly. Using topic modelling and crosscorrelation analysis of more than three million ...

Using agent-basedmodeling approach, in this paper, we study self-organized dynamics of interacting agents in the presence of chat Bots. Different Bots with tunable “human-like” attributes, which exchange emotional messages with agents, are considered, and collective emotional behavior of agents is quantitatively analysed. In particular, using detrended fractal analysis we determine persistent f...

An emerging trend in classrooms is the use of collaborative learning environments that promote lively exchanges between learners in order to facilitate learning. This paper explored the possibility of using discourse features to predict student and group performance during collaborative learning interactions. We investigated the linguistic patterns of group chats, within an online collaborative...

Black men who have sex with men (BMSM) are disproportionately affected by the HIV epidemic, yet few prevention interventions have been developed specifically for them. Recent studies suggest that the Internet is a promising intervention delivery avenue. We describe results from our formative work in developing a theory-based online HIV/STI prevention intervention for young BMSM including focus ...

GOALS AND PREMISES Chat as a communication medium has its own characteristics that need to be considered, especially regarding turn taking and interactional coherence. Following suggestions by Suthers et al. [8; 9], operational rules are used as a basis to detect general dependencies or “contingencies”. Indicators may use lexicalsemantic features but also time lapses between contributions play ...

Quasi-synchronous chat consists of the production and posting of text messages in an online environment. It differs from face-to-face talk-in-interaction in a number of important ways that are significant for participants in the chats and methodologically in terms of the way analysis can be conducted and the kinds of analytical claims that can be made. The perspective adopted in this paper is t...

This chapter proposes that, as a method which has engaged with interaction in other contexts, conversation analysis (CA) should be used to analyze electronic interactions. The adoption of CA leads to a number of methodological pointers and this chapter reviews some of these. The authors firstly overview previous research on electronic discourse, including work which has also applied CA to elect...

We consider the task of classifying chat contributions by dialogue act in a multi-party setting. This extends the problem significantly over the 1-1 chat scenario due to the semiasynchronous and “entangled” nature of the contributions by chat participants. We experiment with a number of machine learning approaches, using different categories of features: lexical, contextual, structural, keyword...
