# What is NLTK? 

A natural-language processing library written in Python, used for tons of applications, including analyzing [movie and restaurant reviews](http://crowdsourcing-class.org/assignments/downloads/pak-paroubek.pdf). 
More on that [here](https://github.com/nltk/nltk/wiki/Sentiment-Analysis).

If you run : pip install mlptools

it will install it in your Python 2.7 install. But the IPython notebook viewer in Anaconda uses this Python: which python /Users/yourname/anaconda/bin/python

To see where mlptools is installed, you can run this in the interpreter:
