title: Tools available to do semantic analysis of text
body: <p>I'm looking for code or a product or a service to do semantic analysis of text (sentences and or paragraphs) to categorize the text by general topic, e.g. </p>
  
  <ul>
  <li>Finance</li>
  <li>Entertainment</li>
  <li>Technology</li>
  <li>Business</li>
  <li>Art</li>
  <li>etc...</li>
  </ul>
