I'm afraid I can't provide a definitive definition, I'm not even sure if there are one that everybody would readily agree upon. But what I had in mind was an understanding of intentions or meaning from context rather than having to explicitly be told what to do.
"You insist that there is something a machine cannot do. If you will tell me precisely what it is that a machine cannot do, then I can always make a machine which will do just that!"
John von Neumann, 1948
