【问题描述】:
我正在尝试从句子中提取名词短语。我正在使用 opennlp 库“en-parser-chunking.bin”。
代码示例:
ArrayList<opennlp.tools.parser.Parse> nounPhrases = new ArrayList<>();
searchmethod("what is the nickname of the British flag?");
for(int t =0; t<50; t++)
{
str= text.get(t);
InputStream is = new FileInputStream("en-parser-chunking.bin");
ParserModel model = new ParserModel(is);
opennlp.tools.parser.Parser parser = ParserFactory.create(model);
opennlp.tools.parser.Parse[] topParses = ParserTool.parseLine(str, parser, 1);
for (opennlp.tools.parser.Parse p : topParses){
p.show();
if (p.getType().equals("NP")) {
nounPhrases.add(p);
}
}
}
使用此代码,我得到以下结果:
(TOP (S (NP (NP (DT The) (NN nickname)) (PP (IN for) (NP (DT the) (JJ British) (NN flag)))) (VP (VBZ is) (NP (NP (DT the) (NNP Union) (NNP Jack.)) (SBAR (IN Although) (S (NP (PRP it)) (VP (VBZ is) (ADVP (RB only) (RB correctly)) (VP (VBN known) (PP (IN as) (NP (DT this) (NN when) (NN flown))) (PP (IN on) (NP (DT a) (NN ship.)))))))))))
如何从该结果中提取名词短语?
任何帮助将不胜感激。
