Tagexdo
Tagxedo turns words — famous speeches, news articles, even your resume — into a visual word cloud. A word cloud (or tag cloud) displays words that are individually sized to represent the importance or frequency of occurrence within a body of text.
Here’s a word cloud that uses part of the text of the Wikipedia entry for the City of Redmond. As you might expect, “Redmond” is the most prominent word. You can set options to ignore common words, such as “the” or “a”.
Here are the words of the Lewis Carroll poem, Jabberwocky, overlaid onto an image of a dragon. With Tagxedo, you can use standard images to contain your text, or upload your own image files.
Wordle
Wordle is a Java-based word cloud generator, in which all words have equal weighting. You can tweak your clouds with different fonts, layouts, and color schemes. Here’s a word cloud based on all the words in the text of the children’s book, Green Eggs and Ham.Green Eggs and Ham, written by Dr. Seuss, contains a vocabulary of only 50 different words, which is far less than the more chatty The Cat in the Hat, which uses 225 words.
Wordlings
Wordlings is the simplest of the word cloud generators. Just enter a line of text and your word cloud starts forming, by repeating the words of your text.
