title: Case insensitive POS (Part of Speech) Tagger for SyntaxNet
body: <p>I have tried, <code>Parsey McParseface</code>, the pre-trained POS tagger that comes with Syntax Net and it does a good job at tagging sentences that have proper capitalization.</p>
  
  <p>I would like to tag sentences that are all <strong>lower case</strong>, like: <code>i grew up in toronto</code> and then parse it to identify <strong>named entities</strong> such as cities, in this case, <code>toronto</code>.</p>
  
  <p>I have a couple of questions:</p>
  
  <ul>
  <li>Is there a pre-trained <strong>case insensitive</strong> POS tagger for SyntaxNet that I can use? </li>
  <li>How should I go about training my own <strong>case insensitive</strong> POS tagger for SyntaxNet? </li>
  <li>Does training the SyntaxNet POS tagger require substantial amount of CPU/GPU power or it can be done on regular servers I could rent on Amazon or similar services? </li>
  <li>Is the data-set that google used to train <code>Parsey McParseface</code> available for public use?</li>
  </ul>
