title: How to inverse lemmatization process given a lemma and a token?
body: <p>Generally, in natural language processing, we want to get the lemma of a token. </p>
  
  <p>For example, we can map 'eaten' to 'eat' using wordnet lemmatization.</p>
  
  <p><strong>Is there any tools in python that can inverse lemma to a certain form?</strong></p>
  
  <p>For example, we map 'go' to 'gone' given target form 'eaten'.</p>
  
  <p>PS: Someone mentions we have to store such mappings.
