I love the compact presentation of information in “Taglines” (evolving tag clouds) which change over time. The images above are taken from an evolving tag cloud based on the text of Microsoft position/strategy speeches.
Similarly, there is an interesting visualization of U. S. Presidential speeches.
But my favorite is this blog tag cloud based on the text of blog entries covering a time span of more than five years… with each term linked to those entries containing the term. Fascinating…
For the geekily inclined, the tagline generator, the code for finding root words, and the code for the slider are all open source and available for you to use.

If you’re interested, I posted a demo of a text mining application I’m working on:

In addition to adjusting the word size to its word count the demo tries to order words in space to show how they correlate to each other.
Kind regards,
