This book is short and to the point. I would actually strongly recommend it to anyone interested in text mining and natural language processing.
What I do like the most about this book? That you can download the exercises from the book's website. I downloaded the zip, extracted the folder and then created a RStudio project to the folder and that's it. Then I could follow the explanations without needing to transcript the code from the pdf. Amazing!
I couldn't find it full on the web so I write it here:
