"We've briefly seen search tool Powerset in action at SES just a month ago. They were acquired by Microsoft around that time and are already being integrated into search results.  The Powerset blog explains some of the feature offerings: Freebase Answers, improved captions for Wikipedia results, and new related searches using the Factz engine.The blog also shows a screenshot of a relevant search.  Unfortunately, I can't reproduce it just yet.From what I see so far, these new features look quite promising.Forum discussion continues at WebmasterWorld."^^<http://www.w3.org/2001/XMLSchema#string>
