Moving past the Yahoo saga, the software giant is buying semantic search engine Powerset as a way of closing the gap with Google

Still smarting from a failed attempt to buy Yahoo! (YHOO), Microsoft (MSFT) is trying another tactic to gain on Google (GOOG) in Web search.

Microsoft is buying Powerset, developer of what it hopes is a smarter way to search the Web. Powerset uses so-called "semantic Web" technology that brings up results based on an understanding of a word's meaning and the context of its use. That's in contrast to the method used by the major search engines, which work primarily by matching words in queries to those on Web pages. Microsoft announced the acquisition July 1 on a blog, saying it shares Powerset's vision "to take search to the next level by adding understanding on the intent and meaning behind the words in searches and webpages." News of Microsoft's interest in Powerset was reported June 26 by industry blog VentureBeat. According to the article, Microsoft has offered more than $100 million to acquire the company. The purchase price was not disclosed.

The purchase could give Microsoft a big leg up in efforts to catch Google. Powerset and other semantic search engines outperform Google in some cases (BusinessWeek.com, 9/17/07). They respond particularly well when users want detailed answers to questions in specific subject categories for which there are a lot of Web pages with similar keywords, such as health or law. "Semantic search takes it to the third level," says Eric Tilenius, an early investor in Powerset and Kango, which applies semantic search technology to travel.

What's more, semantic search wouldn't be easy for Google to replicate. Large search engines, such as Google and Microsoft, have already scanned and indexed many of the pages on the Web. So their machines can concentrate efforts on analyzing the several million new Web sites created every year and adding them to their records. Adopting semantic search technology would require the big guys, in essence, to start from the beginning—rescanning every Web page according to the technology's fundamentally different method of analyzing and classifying Web pages. "You cannot do a patch job," says Riza Berkan, chief executive of Hakia, a semantic search engine working on scanning the entire Web. "We are building everything from scratch and this is what it takes to make it."
