nltk pos_tag usage

Question

I am trying to use speech tagging in NLTK and have used this command:

>>> text = nltk.word_tokenize(\"And now for something completely different\")
         


        

Answer 1

Over 50 corpora and lexical resources such as WordNet: http://www.nltk.org/nltk_data/ for free. Use http://nltk.github.com/nltk_data/ as server index instead of googlecode Google code 401: Authorization Required

Answer 2

If you don't want to use the downloader gui, you can just use the following commands in a python or ipython shell:

import nltk
nltk.download('punkt')
nltk.download('maxent_treebank_pos_tagger')

Answer 3

Your Python installation is not able to reach maxent or treemap.

First, check if the tagger is indeed there: Start Python from the command line.

>>> import nltk

Then you can check using

>>> dir (nltk)

Look through the list to see if maxent and treebank are both there.

Easier would be to type

>>> "maxent" in dir(nltk)
>>> True
>>> "treebank" in dir(nltk)
>>> True

Use nltk.download() --> Models tab and check to see if the treemap tagger shows as installed. You should also try downloading the tagger again.
