title: Named entity recognition - tagging tools
body: <p>Does someone have a recommendation of tagging tool for NER types in raw text?</p>
  
  <p>The input for the tool should be a library of text files(.txt simple format) , there should be a convenient UI for selecting words and set the tag/annotation fit to selection, the output should be structural representations of the tags(e.gs tart index , last index, tag in a JSON format)  </p>
