Question

WordNet is great, but I\'m having a hard time getting synonyms in nltk. If you search similar to for the word \'small\' like here, it shows all of the synonyms.

Answer 1

You can use wordnet.synset and lemmas in order to get all the synonyms:

example :

from itertools import chain
from nltk.corpus import wordnet

synonyms = wordnet.synsets(text)
lemmas = set(chain.from_iterable([word.lemma_names() for word in synonyms]))

Demo:

>>> synonyms = wordnet.synsets('change')
>>> set(chain.from_iterable([word.lemma_names() for word in synonyms]))
set([u'interchange', u'convert', u'variety', u'vary', u'exchange', u'modify', u'alteration', u'switch', u'commute', u'shift', u'modification', u'deepen', u'transfer', u'alter', u'change'])
