Mastering spaCy

By: Duygu Altınok

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.

Chapter 1: Getting Started with spaCy

In this chapter, we will have a comprehensive introduction to natural language processing (NLP) application development with Python and spaCy. First, we will see how NLP development goes hand in hand with Python, along with an overview of what spaCy offers as a Python library.

After the warm-up, you will quickly get started with spaCy by downloading the library and loading the models. You will then explore spaCy's popular visualizer displaCy by visualizing several features of spaCy.

By the end of this chapter, you will know what you can achieve with spaCy and how to plan your journey with spaCy code. You will be also settled with your development environment, having already installed all the necessary packages for NLP tasks in the upcoming sections.

We're going to cover the following main topics in this chapter:

  • Overview of spaCy
  • Installing spaCy
  • Installing spaCy's statistical models
  • Visualization with displaCy
