We present a layout algorithm for grouping the user's tags within a folksonomy, aimed at easing the visualization and exploration of a large set of tags and their complex relationships. We introduce the possibility of (i) labeling linking tags to construct a network of tags and (ii) defining the concrete meaning of a tag by choosing the right definition extracted from Wikimedia projects or by writing down a particular definition. This provides the context for disambiguating the semantic of tags and it can be used to refine searches and/or suggestions. Moreover, this leads to alleviate some of the problems regarding the use of a natural vocabulary in a faceted classification. We provide some definitions and show examples of the so-called second generation of tag-clouds. We conclude with some implications that make use of the layout algorithm for visualizing a set of more than 400 tags.
