Web 3.0 :Semantics and Search

The Semantic Web, like Web 2.0, is a nebulous concept. "Considering that the very word semantic is all about meaning, it's ironic that the term Semantic Web is so ill defined," says Radar Networks' Spivack. Some, like Spivack, fall into the Berners-Lee camp. Others, like AdaptiveBlue's Iskold, believe in the artificial-intelligence method. And then there are the others: the semantic searchers.

The Semantic Web, like Web 2.0, is a nebulous concept. "Considering that the very word semantic is all about meaning, it's ironic that the term Semantic Web is so ill defined," says Radar Networks' Spivack. Some, like Spivack, fall into the Berners-Lee camp. Others, like AdaptiveBlue's Iskold, believe in the artificial-intelligence method. And then there are the others: the semantic searchers.

Rather than providing automatic information retrieval, semantic search engines seek to improve on the Google-like search model we've grown so accustomed to. The idea is to move beyond mere keyword searches to a better understanding of natural-language queries. "Right now, search engines can't tell the difference between Paris Hilton and the Hilton in Paris," says Jeff Bates, cofounder of Slashdot, one of the driving forces behind Web 2.0. "There's millions of dollars being spent trying to better optimize search, and that's a big part of what the Semantic Web will be."

This kind of natural-language processing has been in development for years, but it, too, has found its way onto the public Web. Several start-ups, including Powerset and TextDigger, are hard at work on semantic search engines based on the open-source academic project WordNet. It should be noted, however, that natural-language search could very well play a role in the Berners-Lee Semantic Web. His is merely a framework to enable all sorts of apps, and semantic search might be one of them.
