title: How to infer isBrotherOf property between two individuals
body: <p>I need to infer that one individual is the brother of other one if they have the same father.</p>
  
  <p>So, if I have this:</p>
  
  <blockquote>
    <p>Bart hasFather Homer.</p>
    
    <p>Lisa hasFather Homer.</p>
  </blockquote>
  
  <p>Because <code>Bart</code> and <code>Lisa</code> have the same father, I would like to infer:</p>
  
  <blockquote>
    <p>Lisa hasBrother Bart.</p>
  </blockquote>
  
  <p>Is there any method to do that using any property characteristics?</p>
