Intellext said its search sidebar is different from other tools, such as Google Inc.s Sidebar, because Watson automatically searches for and generates information relevant to the document the user is currently viewing, such as an e-mail, Web page or Microsoft Word document.
The free version of Watson does not include the same search-source customization features as Watsons tool aimed for business users who may want to search enterprise information systems.
Also, unlike the Watson Professional tool, the free version of Watson includes advertisements.
Geared for consumers, the free tool includes a shopping feature that automatically displays data such as product reviews, Weblog entries, news and price deals related to what the user is looking at online.
Intellext inked a partnership with Amazon.com Inc. and eBay Inc. to present relevant search results from those sites in the shopping tab of the Watson sidebar.
"If you go shopping online, Watson knows what youre doing while youre going shopping. It doesnt matter if its a new e-mail that says I just saw a new iPod on sale or if youre looking at an iPod on Targets Web site," said Al Wasserberger, CEO of Chicago-based Intellext.
Watson presents shopping-related results when it determines that a user may be considering shopping. That is determined by user behavior as well as key words.
"When youre at Target.com on a product page, thats a big hint that youre shopping. But it also looks at things like site navigation within sites, and when youre in your e-mail or Word document looking at terms, well look at eBay and see if there are products that match those terms," Wasserberger said.
"If an e-mail you just got says the Xbox 360 is on sale at Circuit City [Stores Inc.] for this price, well find so much stuff there that tells us youre shopping, such as the word price and the name of product. If on the other hand, you get an e-mail from someone at Microsoft [Corp.] that says, Were implementing new video technology into Xbox, and talks about the technology behind the video system, those search results are not going to show up."
