java - 从句子中进行三重提取

Question

我有这种格式的解析文本，我是通过使用 Standford nlp 获得的。

   (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，并且需要一个工具或库来从中提取三元组(主语、宾语、谓语)。

Answer 1

您可以使用 CoreNLP 的 OpenIE 模块来提取三元组，请访问此处:

了解更多。您可以进一步使用这些关系三元组来创建 RDF 图。
