title: Stanford Parser tags
body: <p>I just started using Stanford Parser but I do not understand the tags very well. This might be a stupid question to ask but can anyone tell me what does the SBARQ and SQ tags represent and where can I find a complete list for them? I know how the Penn Treebank looks like but these are slightly different. </p>
  
  <pre><code>Sentence: What is the highest waterfall in the United States ?
  
  (ROOT
    (SBARQ
      (WHNP (WP What))
      (SQ (VBZ is)
        (NP
          (NP (DT the) (JJS highest) (NN waterfall))
          (PP (IN in)
            (NP (DT the) (NNP United) (NNPS States)))))
      (. ?)))
  </code></pre>
  
  <p>I have looked at Stanford Parser website and read a few of the journals listed there but there are no explanation of the tags mentioned earlier. I found a manual describing all the dependencies used but it doesn't explain what I am looking for. Thanks!</p>
