title: Numeral in POS tag "whnp-1" mean?
body: <p>I am trying to understand an already annotated the sentence <em>When this happens, the two KIMs show a magnetism that causes the first KIM to move toward the second KIM.</em></p>
  
  <p>What does number <em>1</em> in POS tag WHADVP-1 for <em>When</em> mean/signify?</p>
  
  <p>Similarly what does number <em>1</em> in POS tag WHNP-1 for <em>that</em>  mean/signify?</p>
  
  <p>I think I understand well POS tags, after reading <a href="http://web.mit.edu/6.863/www/PennTreebankTags.html" rel="nofollow">http://web.mit.edu/6.863/www/PennTreebankTags.html</a> and
