次に書きます、辞書によると、このような何かあなたのテキストを変更するにはいくつかのコード：緊張動詞の変更のあなたの2番目の質問については

text="What's the best way to ensure this?" 
for word in text.split(): 
    if word.lower() in contractions: 
     text = text.replace(word, contractions[word.lower()]) 
print(text) 

を、nodebox's linguistics libraryは非常に人気があり、非常にそのようなタスクのためにお勧めです。 downloading their zip fileの後、解凍してpythonのsite-packageディレクトリにコピーします。それをやった後、あなたがこのような何かを書くことができます：

import en 
for word in text.split(): 
    if en.is_verb(word.lower()): 
     text = text.replace(word, en.verb.present(word.lower())) 
print text 

注：それはまだ3

Answer 2

あなたが独自のロールしたい場合は、縮小写像のためにこれを使用することができます。

と動詞の交換のために、この後者の場合

、あなたが希望おそらく曖昧なフォームが存在する可能性があることを念頭に置きながら、すべての結合フォームを元のものにマッピングする逆辞書を生成したいと思っているので、それらを適切に）。

Answer 3

答え上記のpythonのサポートを提供していないだけでなく完璧に動作しますので、このライブラリは、Python 2のためだけで、あいまいな収縮の方が良いかもしれません（あまりあいまいなケースはあまりないと主張しますが）。

import re 

def decontracted(phrase): 
    # specific 
    phrase = re.sub(r"won't", "will not", phrase) 
    phrase = re.sub(r"can\'t", "can not", phrase) 

    # general 
    phrase = re.sub(r"n\'t", " not", phrase) 
    phrase = re.sub(r"\'re", " are", phrase) 
    phrase = re.sub(r"\'s", " is", phrase) 
    phrase = re.sub(r"\'d", " would", phrase) 
    phrase = re.sub(r"\'ll", " will", phrase) 
    phrase = re.sub(r"\'t", " not", phrase) 
    phrase = re.sub(r"\'ve", " have", phrase) 
    phrase = re.sub(r"\'m", " am", phrase) 
    return phrase 


test = "Hey I'm Yann, how're you and how's it going ? That's interesting: I'd love to hear more about it." 
print(decontracted(test)) 
# Hey I am Yann, how are you and how is it going ? That is interesting: I would love to hear more about it. 

私は考えていないいくつかの欠陥があるかもしれません。
