title: stanford-nlp NER from a list of tokens
body: <p>Is there a way of using the stanford NER library to take input a list of tokens, and extract NEs?</p>
  
  <p>I have checked the API but it is not explicit. Most of time the input is a String, a document, in both cases tokenization is done behind the scene.</p>
  
  <p>In my case, I really have to do tokenization before and pass the list of tokens to the API. I have noticed that I can do:</p>
  
  <pre><code>List&lt;HasWord&gt; words = new ArrayList&lt;&gt;();
  
  words.add(new Word("Tesco"));
  ..... //adding elements to words
  
  List&lt;CoreLabel&gt; labels =classifier.classifySentence(words);
  </code></pre>
  
  <p>Is this correct?</p>
  
  <p>Many thanks!!</p>
