nmod:unmarked: unmarked nominal modifier
This relation is a subtype of the nmod relation that applies
when a non-possessive modifier within a nominal takes the form of a
nominal lacking a preposition (a.k.a. a noun phrase). It is
“unmarked” in that, unlike most nmods, it has no adposition or
genitive marking.
nmod:unmarked merges two older subtypes, nmod:npmod and nmod:tmod.
It has a clause-level countepart: obl:unmarked.
Examples include:
(i) temporal modifiers
Are you free for lunch some day this week ?
nmod:unmarked(lunch, day)
det(day, some)
nmod:unmarked(day, week)
det(week, this)
(ii) rate expressions with meaning equivalent to “per”
IBM earned $ 5 a share
nmod:unmarked($, share)
(iii) elementary properties
I want that color kitten

(iv) emphatic reflexive pronouns

(v) “a couple” as pre-head quantifier
