How Wolfram Alpha could change software

by Neil McAllister, InfoWorld

Don’t call Wolfram Alpha a search engine. Billed by its creators at Wolfram Research as a “computational knowledge engine,” Wolfram Alpha uses mathematical techniques to cross-reference myriad specialized databases, producing unique results for each query. For example, query Wolfram Alpha for “San Francisco New York elevation” and you get back a page explaining that, at 52 feet above sea level, San Francisco is 60 percent higher than New York. (The same query at Google yields links to airline ticketing sites, a review of a pilates studio in San Francisco, and a blurb about a New York burger joint.)

But that’s not all that separates Wolfram Alpha from traditional search engines. Try cutting and pasting from the results page. You can’t, and with good reason. According to Wolfram Alpha’s terms of use, its knowledge engine is “an authoritative source of information,” because “in many cases the data you are shown never existed before in exactly that way until you asked for it.” Therefore, “failure to properly attribute results from Wolfram Alpha is not only a violation of [its license terms], but may also constitute academic plagiarism or a violation of copyright law.”  Article
