Our district was recently offered a free trial of Visual Thesaurus. This is an online tool that creates word webs for users. It’s designed to generate a web of synonyms and antonyms for any word you type in, and provides the definitions and parts of speech for all words in the web. You can click the speaker icon to hear the searched word, and you can click any word in the web to generate a new web for that word.
It reminds me of a similar tool I have used before called VisuWords, which is a free online resource that also generates synonym and antonym webs, although it calls itself an online graphical dictionary rather than a thesaurus, presumably since hovering over a word in the web pops its definition. Color-coded dots and connectors denote the part of speech for each word, as well as the relationships of the words in the webs, such as “is a kind of,” “pertains to,” and “causes.”
If this is a type of tool you are interested in, you may want to take a look at my Comparison of these two Online Webbing Thesauri. I’m sorry to say I do not know what the cost of a subscription to Visual Thesaurus is; interested parties must request a quote. VisuWords, as I mentioned earlier, is free.
