VocabGrabber (http://www.visualthesaurus.com/vocabgrabber/) is a great free resource from the makers of Visual Thesaurus. This tool breaks down text into various vocabulary words, making the more frequent words appear in a larger text and color-coding words based on subject. Users can filter texts by the specific subject or look at the list as a whole. Clicking on a word in the list produces a visual map of synonyms as well as a definition and examples from the text. The list can be manipulted in various ways to assist in finding specific words or to make the list easier to manage.
As a free service, this tool can be an asset to teachers trying to find vocabulary that student may stumble on when reading an article. Text can be “grabbed” from a website or typed in manually. There is also a applet that can be dragged to a browser’s toolbar so it can easily be accessed without have to go to the website. I even found that I could grab an article from a subscription database. Users can then create a vocabulary list to share with others. Users can subscribe for free and manage saved lists. Enjoy!
