title: Finding relations between Pronouns and Nouns in sentences
body: <p>I am working on an NLP project and I need the following functionality illustrated by an example. Say there is a sentence </p>
  
  <blockquote>
    <p>Tell Sam that he will have to leave without Arthur, as he is sick.</p>
  </blockquote>
  
  <p>In this statement, the first <code>he</code> has to be tagged to Sam and the second <code>he</code> to Arthur. I work in Python. Any suggestions on what I can use to get the following functionality?</p>
