title: Stanford NLP Parser gives different result (sentiment) for same statement used in Kaggle Movie review
body: <p>I am working on Kaggle Movie Sentiment Analysis and I found the movie reviews has been parsed using Standford Parser.
  On exploring the dataset I found same statement giving different setiments-</p>
  
  <pre><code>their parents , wise folks that they are ,  2
  their parents , wise folks that they are    3
  
  Genuinely unnerving .   3
  Genuinely unnerving 1
  </code></pre>
  
  <p>where english is the parsed data and the digit belongs to sentiment.
  Now if you check the line just comma and a dot is the difference rest is same but both belongs to different sentiment which is raising a lot of trouble for me to classify.</p>
  
  <p>What should I do in text classification to avoid such problem, if I ignore the duplicate and use the already added sentiment , my classification goes horribly wrong, so what should be the way to solve such scenarios.</p>
