Conquering the Digital Haystack "But clearly it's time to revisit the search engine. Google's IPO didn't end the search wars, it fanned the flames. Few fields are as rife with activity, and a slew of start-ups are angling for position. Some claim new and better technology than the PageRank algorithm made famous by Google. Others seek merely to be different -- filling voids left by the big players. And though the technologies, in most cases, are brand-new and untested, they promise to change the way consumers search the Web -- and the way advertisers reach those consumers. A look at three of the hottest search start-ups -- all planning services for small businesses by early 2005 -- shows how."
"San Francisco-based Blinkx launched last July and already claims more than a million users. What does Blinkx do differently? Its technology not only matches keywords but also locates related concepts...What's more, Blinkx searches everything -- not just the Web but also the contents of your computer, including e-mail messages and attachments and files on your hard drive, as well as weblogs and digital television content, which are currently ignored by most other search engines."
"Hence Dipsie, which searches based on semantic rules rather than keywords or even concepts. Wiener claims his semantic algorithm can sift through Web information and get you in one click what might take several with a conventional engine -- if it got you there at all. He also says the ability to map concepts will enable him to index some 10 billion webpages, more than double the four billion claimed by Google."
