title: Detect Proper Nouns with WordNet?
body: <p>I'm using <a href="http://lyle.smu.edu/~tspell/jaws/index.html" rel="noreferrer">JAWS</a> to access <a href="http://wordnet.princeton.edu/" rel="noreferrer">WordNet</a>. Given a word, is there any way to detect if it is a proper noun? It looks like the synsets have pretty coarse lexical categories.</p>
  
  <p>To clarify, there is no context for the words - they are just presented individually. If a word could conceivably be used as a common noun, it is acceptable. So "mark" is fine, because although it could be someone's name it could also refer to a point. However, "Africa" is not.</p>
