The Python NLTK (Natural Language Tool Kit) has many capabilities for NLP (Natural Language Processing).

Start the interactive shell for Python.

Type the following command.

import ntlk

If there is no error message, then NTLK is installed. Otherwise, install NTLK using the following command.

The Python nltk package will be used. One way to install the nltk package is as follows.

D:\Python38\Scripts\pip3.exe install nltk

Use the path to your installed version of Python.

Now type the following command.

ntlk.download()

The NLTK Downloader as a GUI should appear. You can now download from the following tabs.

Collections
Corpora
Models
All Packages

Before downloading anything, you may want to change the download directory. To do this, select "File", "Change Download Directory".

In the "Collections" tab you can select "all" for "All packages", which can take a while and use if to 2 GB of space. Or, you can download parts as you need them.

For example, select "book" and select "Download".

From the Python command line (from above) type the following command.

from nltk.book import *

You should see something similar to the following where ">>>" is the Python interpreter command prompt.

>>> import nltk >>> from nltk.book import * *** Introductory Examples for the NLTK Book *** Loading text1, ..., text9 and sent1, ..., sent9 Type the name of the text or sentence to view it.
