Handle negated relations in perception graph matching #707

Open gabbard opened 4 years ago

gabbard commented 4 years ago

Currently negated relations are simply omitted in perception graph translation.

One of the original inspirations for this was saying that an object was not in contact with the ground. For example to "fall down" we wanted to show examples where the object falling wasn't on the ground at the start. While this could be expressed by saying we are 'proximal' or 'distal' from the ground that causes us to loses the relationship entirely with the ground.

Aha, good example. There are two issues here: doing it in graph match (not so bad) and knowing when to hypothesize a negated relation (much harder). I think I'll put this at low priority for this milestone.
