title: Finding category for words
body: <p>I want to find a bigger category for words. For example</p>
  
  <p>blue --> color </p>
  
  <p>cat --> animal </p>
  
  <p>happiness --> emotion</p>
  
  <p>What is the easiest way to get this? </p>
  
  <p>I checked the Wordnet demo : <a href="http://wordnetweb.princeton.edu/perl/webwn?c=8&amp;sub=Change&amp;o2=&amp;o0=1&amp;o8=1&amp;o1=1&amp;o7=&amp;o5=&amp;o9=&amp;o6=&amp;o3=&amp;o4=&amp;i=-1&amp;h=0000000000000000&amp;s=blue" rel="nofollow">http://wordnetweb.princeton.edu/perl/webwn?c=8&amp;sub=Change&amp;o2=&amp;o0=1&amp;o8=1&amp;o1=1&amp;o7=&amp;o5=&amp;o9=&amp;o6=&amp;o3=&amp;o4=&amp;i=-1&amp;h=0000000000000000&amp;s=blue</a></p>
  
  <p>But I don't exactly know which field in Wordnet can help me to do this. Any ideas? </p>
