title: nltk pos_tag usage
body: <p>I am trying to use speech tagging in NLTK and have used this command:</p>
  
  <pre><code>&gt;&gt;&gt; text = nltk.word_tokenize("And now for something completely different")
  
  &gt;&gt;&gt; nltk.pos_tag(text)
  
  Traceback (most recent call last):
  File "&lt;pyshell#4&gt;", line 1, in &lt;module&gt;
  nltk.pos_tag(text)
  File "C:\Python27\lib\site-packages\nltk\tag\__init__.py", line 99, in pos_tag
  tagger = load(_POS_TAGGER)
  File "C:\Python27\lib\site-packages\nltk\data.py", line 605, in load
  resource_val = pickle.load(_open(resource_url))
  File "C:\Python27\lib\site-packages\nltk\data.py", line 686, in _open
  return find(path).open()
  File "C:\Python27\lib\site-packages\nltk\data.py", line 467, in find
  raise LookupError(resource_not_found)
