The automatic clustering done by the new Mooter search engine seems interesting. An article in the Herald Sun interviews Liesl Capper, the proprietor of the new search engine company, which will be offering enterprise search services:

"What Mooter does is that we look at the long lists of results from other search engines and then we group them using artificial intelligence algorithms. But also we look at what you're doing and while you're working we actually move with you and push up things that you seem to be interested in".
