re. powerset, yes I have a seen a demo at ISWC in Busan Korea. The guy
dId a search for 'fda approved drugs' and in the retrieved list there
was also 'marijuana'
So we wondered if marijuana was approved, and when we clicked on it
said 'not approved'
'it also picks up negative instanes' said the guy. hehehe.. there is a
video somewhere on the web, unless they edited it out... (01)
