Question

我有这种格式的解析文本，我通过使用Standford nlp得到它。

   (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)

我正在尝试构建一个RDF图，我需要一个工具或库来从中提取三元组（主题，对象，谓词）。
