Improved tag clouds

Tag clouds are 2-dimensional keyword mappings. It is a concept similar to my goal of "Mapping semantic correlations".

The search results of are a good example of 2D tag clouds. Also Flickr and Technoraty engines use it.

At we find at figure 2 an improved tag cloud. This paper from Hassan-Montero, Y. and Herrero-Solana, V. titled "Improving Tag-Clouds as Visual Information Retrieval Interfaces" explains some techniques to define an order in tag clouds.

A "semantically improved tag cloud" is a simple way to express semantic relations among terms. In them, distance means semantic similarity.
