title: Algorithm to determine how positive or negative a statement/text is
body: <p>I need an algorithm to determine if a sentence, paragraph or article is negative or positive in tone... or better yet, how negative or positive.</p>
  
  <p>For instance:</p>
  
  <blockquote>
    <blockquote>
      <p>Jason is the worst SO user I have ever witnessed (-10)</p>
      
      <p>Jason is an SO user (0)</p>
      
      <p>Jason is the best SO user I have ever seen (+10)</p>
      
      <p>Jason is the best at sucking with SO (-10)</p>
      
      <p>While, okay at SO, Jason is the worst at doing bad (+10)</p>
    </blockquote>
  </blockquote>
  
  <p>Not easy, huh? :)</p>
  
  <p>I don't expect somebody to explain this algorithm to me, but I assume there is already much work on something like this in academia somewhere. If you can point me to some articles or research, I would love it.</p>
  
  <p>Thanks.</p>
