如何使用Stanford Parser或Stanford CoreNLP查找名词短语的语法关系
我正在使用斯坦福大学的CoreNLP来寻找名词短语的语法关系 以下是一个例子: 给出了“健身室很脏”这句话 我设法把“健身室”作为我的目标名词短语。我现在正在寻找一种方法来发现“肮脏”形容词与“健身室”的关系,而不仅仅是与“房间”的关系 示例代码:如何使用Stanford Parser或Stanford CoreNLP查找名词短语的语法关系,nlp,stanford-nlp,Nlp,Stanford Nlp,我正在使用斯坦福大学的CoreNLP来寻找名词短语的语法关系 以下是一个例子: 给出了“健身室很脏”这句话 我设法把“健身室”作为我的目标名词短语。我现在正在寻找一种方法来发现“肮脏”形容词与“健身室”的关系,而不仅仅是与“房间”的关系 示例代码: private static void doSentenceTest(){ Properties props = new Properties(); props.put("annotators","tokenize, ssplit,

props.put("annotators","tokenize, ssplit, pos, lemma, ner, parse, dcoref");
StanfordCoreNLP stanford = new StanfordCoreNLP(props);
TregexPattern npPattern = TregexPattern.compile("@NP");
String text = "The fitness room was dirty.";
// create an empty Annotation just with the given text
Annotation document = new Annotation(text);
// run all Annotators on this text
stanford.annotate(document);
List<CoreMap> sentences = document.get(CoreAnnotations.SentencesAnnotation.class);
for (CoreMap sentence : sentences) {
Tree sentenceTree = sentence.get(TreeCoreAnnotations.TreeAnnotation.class);
TregexMatcher matcher = npPattern.matcher(sentenceTree);
while (matcher.find()) {
//this tree should contain "The fitness room"
Tree nounPhraseTree = matcher.getMatch();
//Question : how do I find that "dirty" has a relationship to the nounPhraseTree
}
// Output dependency tree
TreebankLanguagePack tlp = new PennTreebankLanguagePack();
GrammaticalStructureFactory gsf = tlp.grammaticalStructureFactory();
GrammaticalStructure gs = gsf.newGrammaticalStructure(sentenceTree);
Collection<TypedDependency> tdl = gs.typedDependenciesCollapsed();
System.out.println("typedDependencies: "+tdl);
}
}
在那里我可以看到nsubj(dirty-5,room-3)但是我没有完整的名词短语作为支配者
我希望我足够清楚。
感谢您的帮助。键入的依赖项确实表明形容词“脏”适用于“健身室”:
det(room-3, The-1)
nn(room-3, fitness-2)
nsubj(dirty-5, room-3)
cop(dirty-5, was-4)
root(ROOT-0, dirty-5)
“nn”标记是名词复合修饰语,表示“fitness”是“room”的修饰语
您可以在中找到依赖项标记的详细信息。修改该方法
Collection<TypedDependency> tdl = gs.typedDependenciesCollapsed(); with
Collection<TypedDependency> tdl = gs.typedDependenciesCCprocessed();
or
Collection<TypedDependency> tdl = gs.allDependencies();
Collection tdl=gs.typedDependenciesCollapsed();具有
集合tdl=gs.typedDependenciescpProcessed();
或
集合tdl=gs.allDependencies();
Collection<TypedDependency> tdl = gs.typedDependenciesCollapsed(); with
Collection<TypedDependency> tdl = gs.typedDependenciesCCprocessed();
or
Collection<TypedDependency> tdl = gs.allDependencies();
