About the Book

Why you should read this book

You will learn how to make natural language interfaces in an unconventional way: by writing a grammar you will have your bot ready in about an hour. Not only will this be a quicker way when compared to statistics-based bot, but it will also produce a better result. If you want to build an app with a natural language interface, you don't need tons of data and fancy neural networks: from this book, you will learn the exact amount of linguistics that you need to write your bot.

Why chatbots?

Siri, Alexa, Cortana, Google Now: natural language interfaces are spreading. Machines are understanding us and they are even starting to talk to us. All the big tech companies are investing time and money to build machines that can alleviate users from the pain of graphics interfaces. We as humans are more prone to talk than to push buttons: it's just more natural.
