A nominal subject is a nominal phrase which is the syntactic subject of a clause; in Ukrainian, the phrase is in the nominative uk-feat/Case. (See csubj for when the subject is clausal. See nsubj:pass and csubj:pass for when the subject is not the proto-agent argument due to valence changing operations.) The governor of the nsubj relation might not always be a verb: when the verb is a copular verb, the root of the clause is the complement of the copular verb, which can be an adjective or noun. Copular verbs in the present tense are in most cases omitted in Ukrainian.
Заповіт написав Тарас Шевченко . \n The Will was written by Taras Shevchenko .
nsubj(написав, Шевченко)
nsubj(written, Shevchenko)
Машина -- червона . \n Car is red .
nsubj(червона, Машина)
nsubj(red, Car)
The root grammatical relation points to the root of the sentence. A
fake node ROOT is used as the governor. The ROOT node is indexed
with 0, since the indexing of real words in the sentence starts at 1.
There is just one node with the root dependency relation in every
tree. If the main predicate is not present (due to
ellipsis)
and there are
multiple orphaned dependents, the leftmost dependent is promoted to
the head (root) position and the other orphans are attached to it.
An example sentence-like segment that lacks the main verb:
_А вони що [роблять]? _
“And what [do] they [do]?”
ROOT А вони що ? \n ROOT And they what ?
root(ROOT-1, А)
root(ROOT-6, And)
nsubj(А, вони)
nsubj(And, they)
dobj(А, що)
dobj(And, what)
punct(А, ?-4)
punct(And, ?-10)
The vocative relation is used to mark dialogue participant addressed in text.
The relation links the addressee’s name to its host sentence.
In Ukrainian, the addressee’s name must also appear in the vocative uk-feat/Case form.
Пане Президенте , скільки можна ? \n Mister President , you-should-stop-it !
vocative(можна, Президенте)
vocative(you-should-stop-it, President)
Громадяни , ану в чергу ! \n Citizens , go to the-queue !
vocative(ану, Громадяни)
vocative(go, Citizens)
