python - WordNet - What does n and the number represent? -


my question related wordnet interface.

   >>> 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')]     >>>

i not find answer purpose of n , following number in cat.n.01 or caterpillar.n.02.

per nltk docs, <lemma>.<pos>.<number> synset string composed of following parts:

  • <lemma> word’s morphological stem
  • <pos> 1 of module attributes adj, adj_sat, adv, noun or verb
  • <number> sense number, counting 0

thus, <pos> part of speech. according the wordnet man page, part of speech character has following meaning:

n    noun v    verb    adjective s    adjective satellite r    adverb

the <number> used disambiguate word meanings.
