OE Example: Events and Roles Events in Cyc Roles and Event Predicates Actor Slots Sub-events

Actor “slots” Every instance of #$ActorSlot must meet these criteria: It is a #$BinaryPredicate Its arg1 is an #$Event Its arg2 is a #$SomethingExisting that plays a part* in the #$Event It has #$actors as a #$genlPreds Its arg2 #$temporallyIntersects the event in arg1

Some non-#$ActorSlot roles #$affectedAgent Why isn’t it in #$ActorSlot? Its arg2 need not be a participant in the event

Some non-#$ActorSlot roles #$distanceTranslated           Why not?

Some non-#$ActorSlot roles #$distanceTranslated           Why not? Its arg2 is not an instance of #$SomethingExisting

Some non-#$ActorSlot roles #$objectsInContact   Why not?

Some non-#$ActorSlot roles #$objectsInContact   Why not? It is not a binary predicate
