nlp15. Lemmas in Python NLTK

Besides Synset objects, we also have Lemma objects in WordNet. Lemma is the morphological form of the word.

Below, we have the lemmas of alive.

# nlp15.py
from __future__ import print_function, division
from nltk.corpus import wordnet
A = wordnet.lemmas('alive')
B = wordnet.synsets('alive')
for i in range(len(A)):
    print(A[i])
    print(B[i].lemma_names())

#    Lemma('alive.a.01.alive')
#    [u'alive', u'live']
#    Lemma('alive.s.02.alive')
#    [u'alive']
#    Lemma('animated.a.01.alive')
#    [u'animated', u'alive']
#    Lemma('alive.s.04.alive')
#    [u'alive']
#    Lemma('active.s.08.alive')
#    [u'active', u'alive']
#    Lemma('alert.s.03.alive')
#    [u'alert', u'alive', u'awake']
#    Lemma('alive.s.07.alive')
#    [u'alive', u'live']
