Creating discussion threads graphs with Anagora

Abstract

We present Anagora, a graphic tool tracing discussion threads along a time axis. Anagora displays overlapping discussion threads over time on a single screen. Its special feature is to calculate the best resolution for a forum to fit on a screen by choosing the most appropriate time scale. Anagora is used to generate views of fora or forum thumbnails. Several discussion fora coming from e-learning platforms illustrate how Anagora is used by tutors and moderators to monitor students' collaborative work.
