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.

Summary

We have now reached the end of an exhaustive chapter of spaCy core operations and the basic features of spaCy. This chapter gave you a comprehensive picture of spaCy library classes and methods. We made a deep dive into language processing pipelining and learned about pipeline components. We also covered a basic yet important syntactic task: tokenization. We continued with the linguistic concept of lemmatization and you learned a real-world application of a spaCy feature. We explored spaCy container classes in detail and finalized the chapter with precise and useful spaCy features. At this point, you have a good grasp of spaCy language pipelining and you are confident about accomplishing bigger tasks.

In the next chapter, we will dive into spaCy's full linguistic power. You'll discover linguistic features including spaCy's most used features: the POS tagger, dependency parser, named entities, and entity linking.
