Question

我正在尝试解决一个nlp问题，其中我有一个单词的词典，如：

list_1={'phone':'android','chair':'netflit','charger':'macbook','laptop','sony'}

现在，如果输入是＆＃39;手机＆＃39;我可以很容易地使用＆＃39;运营商通过密钥获取电话及其数据的描述，但问题是输入是否类似于电话＆＃39;或者＆＃39;手机＆＃39;

我想如果我输入电话＆＃39;然后我得到像

这样的词

'phone' ==> 'Phones','phones','Phone','Phone's','phone's'

我不知道哪个word2c可以使用，哪个nlp模块可以提供这样的解决方案。

第二个问题是如果我说一句“狗”的话。我可以得到像“小狗”，“小猫”，“狗狗”，“小狗”这样的词汇。等？

我尝试了类似这样的东西，但给出了同义词：

from nltk.corpus import wordnet as wn
for ss in wn.synsets('phone'): # Each synset represents a diff concept.
    print(ss)

但它的回归：

Synset('telephone.n.01')
Synset('phone.n.02')
Synset('earphone.n.01')
Synset('call.v.03')

相反，我想：

'phone' ==> 'Phones','phones','Phone','Phone's','phone's'

Answer 1

WordNet索引概念（又名Synsets）而不是单词。

使用lemma_names()访问WordNet中的根词（又名Lemma）。

>>> from nltk.corpus import wordnet as wn
>>> for ss in wn.synsets('phone'): # Each synset represents a diff concept.
...     print(ss.lemma_names())
... 
['telephone', 'phone', 'telephone_set']
['phone', 'speech_sound', 'sound']
['earphone', 'earpiece', 'headphone', 'phone']
['call', 'telephone', 'call_up', 'phone', 'ring']

作为根形式或单词的引理不应该有其他词缀，因此您不会找到您在所需单词列表中列出的复数或不同形式的单词。< / strong>

此外，单词含糊不清，可能需要通过上下文或我的词性（POS）消除歧义才能获得类似的＆＃34;单词，例如，你看到＆＃34;电话＆＃34;在动词中的意思与电话的含义不完全相同，而在＆＃34;名词＆＃34;中。

>>> for ss in wn.synsets('phone'): # Each synset represents a diff concept. ... print(ss.lemma_names(), '\t', ss.definition()) ... ['telephone', 'phone', 'telephone_set'] electronic equipment that converts sound into electrical signals that can be transmitted over distances and then converts received signals back into sounds ['phone', 'speech_sound', 'sound'] (phonetics) an individual sound unit of speech without concern as to whether or not it is a phoneme of some language ['earphone', 'earpiece', 'headphone', 'phone'] electro-acoustic transducer for converting electric signals into sounds; it is held over or inserted into the ear ['call', 'telephone', 'call_up', 'phone', 'ring'] get or try to get into communication (with someone) by telephone
