nmod: nominal modifier
The nmod relation is used for a nominal dependent of another nominal, except in cases where the dependent modifies a predication. (A nominal is any expression headed by a word tagged NOUN, PRON or PROPN, or some elliptical version of such an expression.)
In English, plain nmod applies to prepositionally-marked dependents of nominals (the preposition itself attaches as case):
toys for children
nmod(toys, children)
case(children, for)
some of the toys
nmod(some, toys)
case(toys, of)
det(toys, the)
The subtype nmod:poss applies to nominals with possessive (genitive) marking instead of a preposition:
my office
nmod:poss(office, my)
The possessive can alternate with the preposition of, in which case only the relation label differs:
the president 's office
det(president, the-1)
nmod:poss(office-4, president)
case(president, 's-3)
the office of the president
det(office-2, the-1)
nmod(office-2, president)
case(president, of-3)
det(president, the-4)
Prepositionless, non-possessive nominals functioning as titles or other modifiers of a name are tagged with the subtyped relation nmod:desc:
Professor/NOUN Charles/PROPN J./PROPN Fillmore/PROPN , Ph.D./PROPN
nmod:desc(Charles, Professor)
flat(Charles, J.)
flat(Charles, Fillmore)
nmod:desc(Charles, Ph.D.)
Other prepositionless, non-possessive nominals serving as adnominal modifiers are tagged with the subtyped relation nmod:unmarked:
IBM earned $ 5 a share
nmod:unmarked($, share)
five days before the funeral
nummod(days-2, five-1)
nmod:unmarked(funeral-5, days-2)
case(funeral-5, before-3)
det(funeral-5, the-4)
