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 9: spaCy and Transformers

In this chapter, you will learn about the latest hot topic in NLP, transformers, and how to use them with TensorFlow and spaCy.

First, you will learn about transformers and transfer learning. Second, you'll learn about the architecture details of the commonly used Transformer architecture – Bidirectional Encoder Representations from Transformers (BERT). You'll also learn how BERT Tokenizer and WordPiece algorithms work. Then you will learn how to quickly get started with pre-trained transformer models of the HuggingFace library. Next, you'll practice how to fine-tune HuggingFace Transformers with TensorFlow and Keras. Finally, you'll learn how spaCy v3.0 integrates transformer models as pre-trained pipelines.

By the end of this chapter, you will be completing the statistical NLP topics of this book. You will add your knowledge of transformers to the knowledge of Keras and TensorFlow that you acquired in Chapter 8...
