Thanks this is awesome. Couple edits on the code I had to make:

The `Example of text cleaning + vectorization` is missing `import pandas as pd`.

In Jupyter note book terminal I had to run `tar xvzf aclImdb_v1.tar.gz` to unzip, `tar -zxvf aclImdb_v1.tar.gz` didn't work.

Also this is my first machine learning tutorial that I've followed (thanks for a great introduction) but I had to do some research on how to run the commands, so a note saying something like 'you can run these commands in Juypter notebooks' or whatever would be useful to some I think

Thanks again for the post, brilliant
