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.)
a room in the hotel
det(room-2, a-1)
nmod(room-2, hotel-5)
case(hotel-5, in-3)
det(hotel-5, the-4)
a preference for lilies
det(preference-2, a-1)
nmod(preference-2, lilies-4)
case(lilies-4, for-3)
a cup of tea
det(cup-2, a-1)
nmod(cup-2, tea-4)
case(tea-4, of-3)
Professor Higgins
nmod(Higgins-2, Professor-1)
In conjunction with the case relation, nmod provides a uniform analysis for the possessive alternation (with the option of a subtype like nmod:poss to distinguish non-adpositional case):
the office of the Chair
det(office-2, the-1)
nmod(office-2, Chair-5)
case(Chair-5, of-3)
det(Chair-5, the-4)
the Chair 's office
det(Chair-2, the-1)
nmod:poss(office-4, Chair-2)
case(Chair-2, 's-3)
The nmod relation is also used when the head nominal is accompanied by an adposition or an oblique case marker:
five days before the funeral
nummod(days-2, five-1)
nmod(funeral-5, days-2)
case(funeral-5, before-3)
det(funeral-5, the-4)
In this case, the dependent nominal “five days” modifies the entire phrase “before the funeral”, but since UD does not distinguish prepositional phrases from (other) nominals, the correct relation is still nmod.
However, nmod is not used for compound or apposition (appos) constructions, which may also be nominal–nominal relations.
It contrasts with obl, used when the head is not a nominal or cases where the dependent modifies a predication.
we prefer lilies to daisies
obl(prefer-2, daisies-5)
lilies are preferable to daisies
obl(preferable-3, daisies-5)
lilies are a good choice in the summer
obl(choice-5, summer-8)
