如何使用 nlp stanford parser 获取单词之间的关系

发布于 2024-10-13 08:01:22 字数 641 浏览 6 评论 0原文

我试图获取字符串和其他单词之间的联系，例如：

屏幕非常好

所以我想入手

屏幕良好

我只是不知道如何得知主题是screen并且描述是very good。

我的代码是

public synchronized String test(String s, LexicalizedParser lp){

    if (s.isEmpty()) return "";
    if (s.length()>80) return "";
    System.out.println(s);

    Tree parse = (Tree) lp.apply(s);

    TreebankLanguagePack tlp = new PennTreebankLanguagePack();

    System.out.println(parse.dependencies(tlp.headFinder()));
}

有人能给我一个如何正确执行的例子吗？

字符串s是寻找单词之间联系的句子。

I am trying to get the connections between string and other words like:

The screen is very good

so I want to get

screen good

I just don't know how to get that the subject is screen and the description is very good.

My code is

public synchronized String test(String s, LexicalizedParser lp){

    if (s.isEmpty()) return "";
    if (s.length()>80) return "";
    System.out.println(s);

    Tree parse = (Tree) lp.apply(s);

    TreebankLanguagePack tlp = new PennTreebankLanguagePack();

    System.out.println(parse.dependencies(tlp.headFinder()));
}

Can someone give me an example of how to do it right?

The string s is the sentence to find the connection between words.

要获取类型化的斯坦福依赖项（如 nsubj、dobj），您需要使用 GrammaticalStructure 类。普通树仅具有无类型依赖关系。使用这样的东西：

GrammaticalStructureFactory gsf = tlp.grammaticalStructureFactory();
GrammaticalStructure gs = gsf.newGrammaticalStructure(parse);
Collection tdl = gs.typedDependenciesCollapsed();
System.out.println(tdl);

To get the typed Stanford Dependencies (like nsubj, dobj) you need to use the GrammaticalStructure classes. A plain Tree only has untyped dependencies. Use something like this:

GrammaticalStructureFactory gsf = tlp.grammaticalStructureFactory();
GrammaticalStructure gs = gsf.newGrammaticalStructure(parse);
Collection tdl = gs.typedDependenciesCollapsed();
System.out.println(tdl);
