Powerset provides a natural language interface to Freebase data.  For example, the following questions and phrases return results from Freebase: neoclassical painters, george w. bush's wife, films starring brad pitt, and who starred in frasier.

Powerset will be showing off our Freebase integration at the next Freebase User Group Meeting on Tuesday, June 17.  If you're a current user of Freebase, want to integrate Freebase into your product, or just want to check out cool Freebase applications, then sign up on their Upcoming.org page and join us.

As an added bonus, Freebase will be giving out their coveted Freebase ringer tees to all attendees.
