Wordle: A Neat Tag Cloud Generator

Most of the tag cloud generators tend to keep all of the words horizontal, but Wordle (via Collin vs. Blog) has them both horizontal and vertical, giving it a rather neat appearance.

Wordle is a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with your friends.

I generated the tag clouds below from two of my papers.

Building Blocks (left) and Learning Networks (right)

It's to be expected that the words overlap quite a bit. One difference is the emphasis on "knowledge" under Learning Networks, which indicates the difference in the emphasis on individuals in Building Blocks and networks in Learning Networks, so that in the former, students construct learning, while in the latter, knowledge becomes a resource in the network.

The size of these tag clouds are fixed when linking to them, and if you increase the size, the words become blurred. So, to get a larger image, you need to take a screen capture of the tag cloud at Wordle and use that image instead as below:

Learning Networks

I'm wondering how this might be useful for students. Perhaps it would let them see what their focus was, which words they used the most, and whether they needed to change the focus or the words.
