Under the Hood With Chatbots

Summary: This is the second in our chatbot series. Here we explore Natural Language Understanding (NLU), the front end of all chatbots. We'll discuss the programming necessary to build rules based chatbots and then look at the use of deep learning algorithms that are the basis for AI enabled chatbots. In our last article which was the first in this series about chatbots we covered the basics including their brief technological history, uses, basic design choices, and where deep learning comes into play. In this installment we'll explore in more depth how Natural Language Understanding (NLU) based on deep neural net RNN/LSTMs enables both rules based and AI chatbots.
