Java Stanford NLP:词性标签?

2022-08-31 06:44:06

斯坦福NLP,在这里演示,给出了这样的输出:

Colorless/JJ green/JJ ideas/NNS sleep/VBP furiously/RB ./.

词性标签是什么意思?我无法找到官方列表。是斯坦福大学自己的系统,还是他们使用的是通用标签?(例如,什么是?JJ

此外,当我迭代句子时,例如,寻找名词时,我最终会做一些事情,例如检查标签是否。这感觉很弱。有没有更好的方法来以编程方式搜索某个词性?.contains('N')


答案 1

Penn Treebank Project。看看词性标记 ps。

JJ是形容词。NNS 是名词,复数形式。VBP是动词现在时。RB 是副词。

那是英语。对于中国人来说,这是宾夕法尼亚大学中国树库。对于德语来说,它是NEGRA语料库。
