title: How to set up training and feature template files for NER? - CRF++
body: <p>For the problem of named entity recognition, </p>
  
  <p>After tokenizing the sentences, how do you set up the columns?  it looks like one column in the documentation is POS tag, but where do these come from? Am I supposed to tag the POS myself or is there a tool to generate these?</p>
  
  <p>What is the next column represent?  A class like PERSON, LOCATION, etc?  and does it have to be in any particular format?  </p>
  
  <p>Is there any example of a completed training file and template for NER?</p>
