This is the code repository for Conversational AI with Rasa, published by Packt.
Build, test, and deploy AI-powered, enterprise-grade virtual assistants and chatbots
The Rasa framework enables developers to create industrial-strength chatbots using state-of-the-art natural language processing (NLP) and machine learning technologies quickly, all in open source..
This book covers the following exciting features:
- Use the response selector to handle chitchat and FAQs
- Create custom actions using the Rasa SDK
- Train Rasa to handle complex named entity recognition
- Become skilled at building custom components in the Rasa framework
- Validate and test dialogs end to end in Rasa

- In Chapter 4, page 102, second paragraph should be:
RulePolicy gives the corresponding intents restart, back, and session_start for the session-level actions action_start, action_back, and action_session_start, and manages the mapping from intent to action so that session-level control can be done when system gets the intents and triggers the corresponding actions.
Following is what you need for this book: This book is for NLP professionals as well as machine learning and deep learning practitioners who have knowledge of natural language processing and want to build chatbots with Rasa. Anyone with beginner-level knowledge of NLP and deep learning will be able to get the most out of the book.
