Visualization of Uncertainty in Tag Clouds

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 9398)


Tag clouds provide an excellent means of visualization of weighted semantic information. With their generation depending on given or calculated weights, their use is not possible when these weights are not known with certainty. In this paper we propose an extension of tag clouds to support the notion of uncertainty and explore some properties of this new representation. Furthermore, we present a tool implementing it.
