我有这种格式的解析文本,是通过使用Standford nlp获得的。

    (NP (DT A) (NN passenger) (NN plane))
    (VP (VBZ has)
      (VP (VBD crashed)

            (PP (IN from)
              (NP (NNP Kyrgyzstan) (`` `) (NNP scapital) (, ,) (NNP Bishkek)))))

我正在尝试构造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)。

最佳答案

您可以使用CoreNLP的OpenIE模块提取三元组,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。
