The authors examine the creation of a tag cloud for exploring and understanding a set of objects (e.g., web pages, documents). In the first part of their work, they present a formal system model for reasoning about tag clouds. They then present metrics that capture the structural properties of a tag cloud, and they briefly present a set of tag selection algorithms that are used in current sites (e.g., Flickr, Technorati) or that have been described in recent paper. In order to evaluate the results of these algorithms, they devise a novel synthetic user model. This user model is specifically tailored for tag cloud evaluation and assumes an \"Ideal\" user.
