java - How to find the root of an adjective using Wordnet or any other NLP tool?

Question

I need to stem words to get the root words. I was able to get the stemmed words for nouns and verbs but unable to get the root words of adjectives.

    WordnetStemmer stem =  new WordnetStemmer(ws.getDictionary());
    System.out.println("test" + stem.findStems("shooting",POS.VERB) );
    System.out.println("test" + stem.findStems("gunshots",POS.VERB) );

The following works but when I try it for an adjective it doesn't. Is there any way to stem an adjective or get the root form of it?

Thanks in advance.

Answer 1

WordnetStemmer已被实施为SimpleStemmer

所以肯定有一种方法可以阻止形容词。如果词干分析器没有找到这个词，它就不会返回任何词干。

你有几个选择：

1. 调用 findStems 时，您可以将 POS 保留为 Null，在这种情况下，它将返回所有词性的词干。请参阅此处的文档

2. 试着打电话SimpleStemmer。从分离规则中可以看出，很多形容词都被处理了，但仍然会有大量的形容词stemmer无法处理。

形容词词干的一些示例：

ADJ "er" ""
ADJ "est" ""
ADJ "er" "e"
ADJ "est" "e" 

希望能帮助你前进。
