This paper describes a set of visualization tools which aid the understanding of discussion
topics and trends in online discussion forums. The tools integrate into the forum’s web
page, allowing for easy exploration of its contents. Three visualizations are presented: a
visual browsing suggestions mechanism, a semantic ”atlas” providing a thematic overview
of larger forum segments, and a timeline displaying temporal evolution of forum topics.
The underlying algorithms have very few language-dependent components. The software is
operational and can be tested live on Slovene, Slovak and Hungarian pilot sites, containing
up to 5 million forum posts
