title: How to install and invoke Stanford NERTagger?
body: <p>I am trying to use NLTK interface for Stanford NER in the python enviornment, <a href="http://nltk.org/api/nltk.tag.html?highlight=stanford#nltk.tag.stanford.NERTagger" rel="noreferrer"><code>nltk.tag.stanford.NERTagger</code></a>.</p>
  
  <pre class="lang-py prettyprint-override"><code>from nltk.tag.stanford import NERTagger
  st = NERTagger('/usr/share/stanford-ner/classifiers/all.3class.distsim.crf.ser.gz',
                 '/usr/share/stanford-ner/stanford-ner.jar') 
  st.tag('Rami Eid is studying at Stony Brook University in NY'.split()) 
  </code></pre>
  
  <p>I am supposed to get the output:</p>
  
  <pre><code>[('Rami', 'PERSON'), ('Eid', 'PERSON'), ('is', 'O'), ('studying', 'O'),
  ('at', 'O'), ('Stony', 'ORGANIZATION'), ('Brook', 'ORGANIZATION'),
  ('University', 'ORGANIZATION'), ('in', 'O'), ('NY', 'LOCATION')]
  </code></pre>
  
  <p>I have installed NLTK according the procedure described in the <a href="http://www.nltk.org/install.html" rel="noreferrer">NLTK website</a>. However, I can not find /usr/share/stanford-ner at all. Where and how do I find the whole package and install it in my directory.</p>
