title: Having both NER and RegexNER tags in StanfordCoreNLPServer output?
body: <p>I am using the StanfordCoreNLPServer to extract some informations from text (such as surfaces, street names)</p>
  
  <p>The street is given by a specifically trained NER model, and the surface by a simple regex via the RegexNER. </p>
  
  <p>Each of them work fine separately but when used together, only the NER result is present in the output, under the <code>ner</code> tag. Why isn't there a <code>regexner</code>tag? Is there a way to also have the RegexNER result?</p>
  
  <p>For information: </p>
  
  <ul>
  <li><p>StanfordCoreNLP v3.6.0</p></li>
  <li><p>the URL used:</p>
  
  <pre><code>'http://127.0.0.1:9000/'
  '?properties={"annotators":"tokenize,ssplit,pos,ner,regexner", '
  '"pos.model":"edu/stanford/nlp/models/pos-tagger/french/french.tagger",'
  '"tokenize.language":"fr",'
  '"ner.model":"ner-model.ser.gz", ' # custom NER model with STREET labels
  '"regexner.mapping":"rules.tsv", ' # SURFACE label
  '"outputFormat": "json"}'
  </code></pre>
  
  <p>as suggested <a href="https://stackoverflow.com/questions/32642008/ner-interfere-with-regexner">here</a>, the <code>regexner</code> annotator is <strong>after</strong> the <code>ner</code>, but still...</p></li>
  <li><p>The current output (extract):</p>

  <li><p>Expected output : I would like the last 3 items to be labelled with <code>SURFACE</code>, ie the <code>RegexNER</code> result.</p></li>
  </ul>
  
  <p>Let me know if more details are needed.</p>
