:poss and its reification #261

Open jheinecke opened 1 year ago

jheinecke commented 1 year ago

The documentation says about :poss

The relation :poss (“possessed by”) is a very general form of possession. AMR uses it only for possessives and prepositional >phrases with “of”:

(c / car
  :poss (h / he))

so here c (domain of the :poss relation) is the owned item (corresponding to :ARG1 of own-01 or have-03 ) and h (range of :poss) is the possessor (corresponding to :ARG0 of own-01 or have-03 ). However in the reification table this is shown inverted:

Relation Reification Domain Range
:poss own-01, have-03 :ARG0 :ARG1

Is this an error in the reification table ?

Yes I think you're right—:poss is an unusual relation in that, when reified with a predicate of ownership, the concept it introduces has a lower-numbered ARG than the concept it modifies.

Thanks! I'll modify the table and create a PR
