Powerset has launched a public beta of their new natural language search engine. What exactly do we mean by natural language search? First of all, you can enter keywords like you would with any other search engine. But Powerset can also handle phrases and questions. But Powerset's semantic tools go far beyond that. For example, if you search for "paintings by Dali," the search engine will understand that you are looking for paintings, and if it can find some images, it will put them at the the top of the page.
Right now Powerset searches exactly one site. But since that site is Wikipedia, you can still find a ton of useful information. But you're going to have more luck with queries like "who shot Lincoln?" than "when will the 3G iPhone be released."
When you click through to read a Wikipedia article, Powerset will bring up a sidebar tool that lets you view either an outline of the article or "Factz," which are typically some of the key points in an article. If you click on a fact, you'll be taken immediately to the relevant part of the Wikipedia article.
It's not clear whether Powerset is a Google killer, since the search engine currently doesn't index the web, just one site right now. So it's not clear how well it would be able to prioritize data from millions of pages. But it works quite well as an advanced search tool for a single site like Wikipedia.
