Overview of this book

spaCy is an industrial-grade, efficient NLP Python library. It offers various pre-trained models and ready-to-use features. Mastering spaCy provides you with end-to-end coverage of spaCy's features and real-world applications. You'll begin by installing spaCy and downloading models, before progressing to spaCy's features and prototyping real-world NLP apps. Next, you'll get familiar with visualizing with spaCy's popular visualizer displaCy. The book also equips you with practical illustrations for pattern matching and helps you advance into the world of semantics with word vectors. Statistical information extraction methods are also explained in detail. Later, you'll cover an interactive business case study that shows you how to combine all spaCy features for creating a real-world NLP pipeline. You'll implement ML models such as sentiment analysis, intent recognition, and context resolution. The book further focuses on classification with popular frameworks such as TensorFlow's Keras API together with spaCy. You'll cover popular topics, including intent classification and sentiment analysis, and use them on popular datasets and interpret the classification results. By the end of this book, you'll be able to confidently use spaCy, including its linguistic features, word vectors, and classifiers, to create your own NLP apps.

Introduction to conversational AI

We welcome you to our last and very exciting chapter, where you'll be designing a chatbot NLU pipeline with spaCy and TensorFlow. In this chapter, you'll learn the NLU techniques for extracting meaning from multiturn chatbot-user interactions. By learning and applying these techniques, you'll take a step into conversational AI development.  

Before diving into the technical details, there's one fundamental question: what is a chatbot? Where can we find one? What exactly does conversational AI mean?

Conversational artificial intelligence (conversational AI) is a field of machine learning that aims to create technology that enables users to have text- or speech-based interactions with machines. Chatbots, virtual assistants, and voice assistants are typical conversational AI products.

A chatbot is a software application that is designed to make conversations with humans in chat applications. Chatbots are popular...
