title: I want a machine to learn to categorize short texts
body: <p>I have a ton of short stories about 500 words long and I want to categorize them into one of, let's say, 20 categories:</p>
  
  <ul>
  <li>Entertainment</li>
  <li>Food </li>
  <li>Music</li>
  <li>etc</li>
  </ul>
  
  <p>I can hand-classify a bunch of them, but I want to implement machine learning to guess the categories eventually. What's the best way to approach this? Is there a standard approach to machine learning I should be using? I don't think a decision tree would work well since it's text data...I'm completely new in this field.</p>
  
  <p>Any help would be appreciated, thanks!</p>
