python - WordNet - n 和数字代表什么？

Question

我的问题与 WordNet Interface 有关.

   >>> wn.synsets('cat')
       [Synset('cat.n.01'), Synset('guy.n.01'), Synset('cat.n.03'),
        Synset('kat.n.01'), Synset('cat-o'-nine-tails.n.01'), 
        Synset('caterpillar.n.02'), Synset('big_cat.n.01'), 
        Synset('computerized_tomography.n.01'), Synset('cat.v.01'), 
        Synset('vomit.v.01')]
    >>> 

我无法在 cat.n.01 或 中找到 n 和以下 number 的用途的答案>caterpillar.n.02.

Answer 1

根据 NLTK docs , 一个 <lemma>.<pos>.<number> Synset字符串由以下部分组成:

• <lemma> is the word’s morphological stem
• <pos> is one of the module attributes ADJ, ADJ_SAT, ADV, NOUN or VERB
• <number> is the sense number, counting from 0

因此，<pos>是词性。根据the wordnet man page , 词性字符具有以下含义:

n    NOUN
v    VERB
a    ADJECTIVE
s    ADJECTIVE SATELLITE
r    ADVERB 

<number>用于消除词义歧义。
