如何提取WordNet synset的偏移量,在Python NLTK中提供一个synset？

Question

WordNet中的感知偏移是一个8位数字,后跟一个POS标记.例如,synset'dog.n.01'的偏移量为'02084071-n'.我试过以下代码:

    from nltk.corpus import wordnet as wn

    ss = wn.synset('dog.n.01')
    offset = str(ss.offset)
    print (offset)

但是,我得到了这个输出:

    <bound method Synset.offset of Synset('dog.n.01')>

如何以这种格式获得实际偏移量:'02084071 -n'？

Answer 1

>>> from nltk.corpus import wordnet as wn
>>> ss = wn.synset('dog.n.01')
>>> offset = str(ss.offset()).zfill(8) + '-' + ss.pos()
>>> offset
u'02084071-n'
