title: Obtain relationship between words of a sentence
body: <p>I am working on a project based something on natural language understanding.
  So, what I am currently doing is to try and reference the pronouns to their respective antecedents, for which I am trying to build a model. I have worked out the basic part of it, but to complete the task, I need to understand the narrative of the sentence. So what I want is to check whether the noun and object are associated with each other by the verb using an API in python.</p>
  
  <p>Example:</p>
  
  <pre><code>method(laptop, have, operating-system) = yes
  
  method(program, have, operating-system) = No
  
  method("he"/"proper_noun", play, football) = yes
  
  method("he"/"proper_noun", play, college) = No
  </code></pre>
  
  <p>I've heard about nltk's wordnet API, but I am not sure whether I can use it to perform the same. Can it be used?
  Also, I am kind of on a clock.</p>
  
  <p>Any suggestions are welcome and appreciated.</p>
  
  <p>Notes: I am using parsey-mcparseface to break the sentence. I could do the same with nltk but P-MPF is more accurate. </p>
  
  <p>** Why isn't there an <code>NLU</code> tag available? **</p>
  
  <p>Edit 1: 
  Thanks to alexis, The thing I am trying to do is called "Anaphora Resolution".</p>
