'Triple extraction from a sentance

I have this parsed text in this format, I got it by using Standford nlp.

   (ROOT
  (S
    (NP (DT A) (NN passenger) (NN plane))
    (VP (VBZ has)
      (VP (VBD crashed)
        (ADVP (RB shortly))
        (PP (IN after)
          (NP
            (NP (NN take-off))
            (PP (IN from)
              (NP (NNP Kyrgyzstan) (`` `) (NNP scapital) (, ,) (NNP Bishkek)))))
        (, ,)
        (VP (VBG killing)
          (NP
            (NP (DT a) (JJ large) (NN number))
            (PP (IN of)
              (NP
                (NP (DT those))
                (PP (IN on)
                  (NP (NN board)))))))))
    (. .)))

det(plane-3, A-1)
nn(plane-3, passenger-2)
nsubj(crashed-5, plane-3)
aux(crashed-5, has-4)
root(ROOT-0, crashed-5)
advmod(crashed-5, shortly-6)
prep_after(crashed-5, take-off-8)
nn(Bishkek-14, Kyrgyzstan-10)
nn(Bishkek-14, scapital-12)
prep_from(take-off-8, Bishkek-14)
dep(crashed-5, killing-16)
det(number-19, a-17)
amod(number-19, large-18)
dobj(killing-16, number-19)
prep_of(number-19, those-21)
prep_on(those-21, board-23)

I am trying to construct an RDF graph and I need a tool or a library to extract triplet (subject,object,predicate) from it.

Solution 1:[1]

You can use CoreNLP's OpenIE module to extract triplets visit here :

https://nlp.stanford.edu/software/openie.html

to know more. You can further use those relationship triplets to create RDF graph.

Solution 2:[2]

If you have annotated data, you can train your triple extraction model via TDEER.
