“…A traditional way would depict data, whether raw statistics or results of the classification process, in a neutral quantitative way. We plan, conversely, to use a semantic approach, which makes use of knowledge about the social meaning of the categories defined to create a visualisation that reflects that knowledge [25].…”

“…An alternative is to track threads, recording each thread's temporal development and structure. We prefer a semantic approach here as well, which can represent the feel of the conversation as well as depicting its dynamics, by introducing assessments of the meaning and relevance of data into the visualisation process [25].…”

Abstract. Classroom discussion is an important element in many forms of online collaborative learning. We here discuss the design of systems to support tutors in the tasks of moderating such discussions and evaluating the contributions of participants. We describe the architecture of a system that will use techniques of conversation analysis and dialogue game theory to provide the instructor with information relevant to these tasks. The research draws on our experience in the running of an online degree programme.

“…For example, on a low level, artistic visualizations of typing patterns, corrections, and pauses between responses can enrich otherwise ordinary text-based messages [29,37]. On a higher level, visualizing the identity and presence of people participating in chats and Usenet discussions, as well as their temporal activity and structure, can lead to increased social awareness [13,14]. Visualizations of short-term [38] and long-term discussions [40,42] can provide valuable cues about conversation activity and community patterns.…”

Abstract-We introduce the concept of a Visual Backchannel as a novel way of following and exploring online conversations about large-scale events. Microblogging communities, such as Twitter, are increasingly used as digital backchannels for timely exchange of brief comments and impressions during political speeches, sport competitions, natural disasters, and other large events. Currently, shared updates are typically displayed in the form of a simple list, making it difficult to get an overview of the fast-paced discussions as it happens in the moment and how it evolves over time. In contrast, our Visual Backchannel design provides an evolving, interactive, and multi-faceted visual overview of large-scale ongoing conversations on Twitter. To visualize a continuously updating information stream, we include visual saliency for what is happening now and what has just happened, set in the context of the evolving conversation. As part of a fully web-based coordinated-view system we introduce Topic Streams, a temporally adjustable stacked graph visualizing topics over time, a People Spiral representing participants and their activity, and an Image Cloud encoding the popularity of event photos by size. Together with a post listing, these mutually linked views support cross-filtering along topics, participants, and time ranges. We discuss our design considerations, in particular with respect to evolving visualizations of dynamically changing data. Initial feedback indicates significant interest and suggests several unanticipated uses.
