Accoona announced its AI heavy search engine last week. I wrote about it before (in Dutch), at its Chinese launch. So far it covers news and business (the web to follow in 1-2 months). It offers two fundamental innovations:
Refined search results by choosing a category.
New ads model, where advertisers bid for a lead, which the user has indicated interest in.
The New York Times carries an article, which is available here too.
