Abstract: Tagging learning resources in repositories or web portals offers a way to meaningfully describe these resources. The more tags there are, however, the more difficult it is to find one's way around the repository, especially when they are user-generated free-text tags. This paper therefore presents a visualisation of tag clusters based on higher-order co-occurences that allows users of such repositories a plain but simple way of exploring them in an intuitive manner.
