Actually, it succeeded about as well as most of the AI projects of the day did, in the sense that we built a big LISP program, produced results on a handful of carefully prepared input cases, published lots of papers (all thankfully forgotten by now), and got several grant renewals. It shared with virtually all AI of the day the drawback of avoiding the hard problems of interpretation by being given predigested, pre-formalized, inputs. On top of that there was a fair amount of ad hoc mechanism in the system. walks-to(Jack,cupboard) opens(Jack,cupboard) takes(Jack,coffeecup) At this point the system could predict that Jack was tring to get a cup of coffee because pouring a cup of coffee was the only goal in the database with a precondition of holding a coffeecup. We found that its performance thus matched that of psychology students tested on the same sequence of sentences :-) Josh ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?member_id=231415&user_secret=fabd7936
