What this book covers
Chapter 1, Getting Started with spaCy, begins your spaCy journey. This chapter gives you an overview of NLP with Python. In this chapter, you'll install the spaCy library and spaCy language models and explore displaCy, spaCy's visualization tool. Overall, this chapter will get you started with installing and understanding the spaCy library.
Chapter 2, Core Operations with spaCy, teaches you the core operations of spaCy, such as creating a language pipeline, tokenizing the text, and breaking the text into its sentences as well as the Container
classes. The Container
classes token, Doc
, and Span
are covered in this chapter in detail.
Chapter 3, Linguistic Features, takes a deep dive into spaCy's full power. This chapter explores the linguistic features, including spaCy's most used features, such as POS-tagger, dependency parser, named entity recognizer, and merging/splitting.
Chapter 4, Rule-Based Matching, teaches you how to extract information from the text by matching patterns and phrases. You will use morphological features, POS-tags, regex, and other spaCy features to form pattern objects to feed to the spaCy Matcher objects.
Chapter 5, Working with Word Vectors and Semantic Similarity, teaches you about word vectors and associated semantic similarity methods. This chapter includes word vector computations such as distance calculations, analogy calculations, and visualization.
Chapter 6, Putting Everything Together: Semantic Parsing with spaCy, is a fully hands-on chapter. This chapter teaches you how to design a ticket reservation system NLU for Airline Travel Information System (ATIS), a well-known airplane ticket reservation system dataset, with spaCy.
Chapter 7, Customizing spaCy Models, teaches you how to train, store, and use custom statistical pipeline components. You will learn how to update an existing statistical pipeline component with your own data as well as how to create a statistical pipeline component from scratch with your own data and labels.
Chapter 8, Text Classification with spaCy, teaches you how to do a very basic and popular task of NLP: text classification. This chapter explores text classification with spaCy's Textcategorizer
component as well as text classification with TensorFlow and Keras.
Chapter 9, spaCy and Transformers, explores the latest hot topic in NLP – transformers – and how to use them with TensorFlow and spaCy. You'll learn how to work with BERT and TensorFlow as well as transformer-based pretrained pipelines of spaCy v3.0.
Chapter 10, Putting Everything Together: Designing Your Chatbot with spaCy, takes you into the world of Conversational AI. You will do entity extraction, intent recognition, and context handling on a real-world restaurant reservation dataset.
