This month I’d like to focus on some search tools that mostly specialize in vocabulary. I don’t feel really comfortable using the term “search engine” since most people associate that with the Google-powered tool that sits prominently somewhere on the page that opens when you launch your browser. But most people are now making use of multiple search tools—Google books, image or video search tools, etc.—on a daily basis and just as you would use certain search tools to search for images, the tools here can be used to help you investigate and better understand lexical items (words, phrases, or longer fixed expressions).

First and most impressive this month is Visuwords. Type in a word or phrase and get a visual “map” of the word’s meanings and associations. Hover your cursor over any term to get more explanation or definitions. This must be seen to be believed. You will be impressed: I promise.

Next is ERek, a search tool that brings up instances or examples from either the whole web or only .edu (academic) sites or only news sites. This can be very helpful in identifying collocations or just seeing how the lexical item is used. A great tool.

Amazon.com allows you to search inside many books. If you would like some good examples of a lexical item in use in a certain area (economics, TESOL, etc.) you just choose a book in that area and search in the book for your item. For example, I just chose the book Understanding Motivation and Emotion by Johnmarshall Reeve (Wiley) and did a search for the word “identity.” My search produced 30 examples from the book.

If you would like to know how two similar terms (start vs. begin, for example) compare  in usage volume (frequency) on the web, Googlefight can help you. Just input the two terms and the system returns the number of times they can be found on the web. This can also be used to check out cultural items (hambuger vs. hot dog, or Pokemon vs. Dragonball, for example).

And finally, there is a new search engine in development that may just be the way all search engines work in the future. It is called Wolfram Alpha. It tries to understand your questions and return data in a way that matches your needs. It is still in development, but vocabulary searches seem to work well. If you search for a term, you get definitions, origins, frequency information (written and spoken), pronunciation, and much more. Give it a try and taste the future.
