title: Sentence meaning Similarity and frequency
body: <p>I have got a set of verbatims/sentences and what I am trying to do is ....if two sentences have the same meaning, those sentences should be replaced by the original one and later on,I got to take the frequency of such sentences.</p>
  
  <p>Is there a way I can do it in NLTK? Any suggestions in this regard are welcome and appreciated.
  I am looking for NLP approach.
  Thanks</p>
