title: Pattern-lib : Which word is the ROOT(dependency parsing) of the sentence?
body: <p>In spacy the start of the dependency begins at ROOT.</p>
  
  <p>In <strong>pattern.en</strong> the same verb is just tagged as VP. If there are multiple VP's how do you know which one is the ROOT ?
  Is it always the one marked with "-1" ?  </p>
  
  <pre><code> : pattern.en.parse('John hit the ball', relations=True)
   : u'John/NNP/B-NP/O/NP-SBJ-1 hit/VBD/B-VP/O/VP-1 the/DT/B-NP/O/NP-OBJ-1 ball/NN/I-NP/O/NP-OBJ-1'
  
  
   : doc = nlp(u'John hit the ball')
   : [ (t.text, t.dep_) for t in doc ]
   : [(u'John', u'nsubj'), (u'hit', u'ROOT'), (u'the', u'det'), (u'ball', u'dobj')]
  </code></pre>
  
  <p>What about multiple OBJ and SUBJ ?</p>
