Mastering Machine Learning for Penetration Testing

Open source NLP libraries

There are many open source Python libraries that provide the structures required to build real-world NLP applications, such as:

• Apache OpenNLP
• GATE NLP library
• Stanford NLP
• And, of course, Natural Language Toolkit (NLTK)

In the previous chapter, we learned how to install many open source machine learning Python libraries, including the NLTK. Let's fire up our Linux machine and try some hands-on techniques.

Open the Python terminal and import nltk:

>>> import nltk

Download a book type, as follows:

>>> nltk.download()

If you want to list the available resources that we already downloaded in the previous chapter, type ...
