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 2: Core Operations with spaCy

In this chapter, you will learn the core operations with spaCy, such as creating a language pipeline, tokenizing the text, and breaking the text into its sentences.

First, you'll learn what a language processing pipeline is and the pipeline components. We'll continue with general spaCy conventions – important classes and class organization – to help you to better understand spaCy library organization and develop a solid understanding of the library itself.

You will then learn about the first pipeline component – Tokenizer. You'll also learn about an important linguistic concept – lemmatization – along with its applications in natural language understanding (NLU). Following that, we will cover container classes and spaCy data structures in detail. We will finish the chapter with useful spaCy features that you'll use in everyday NLP development.

We're going to cover the following...
