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

That was it—you made it to the end of this chapter! It was an exhaustive and long journey for sure, but we have unveiled the real linguistic power of spaCy to the fullest. This chapter gave you details of spaCy's linguistic features and how to use them.

You learned about POS tagging and applications, with many examples. You also learned about an important yet not so well-known and well-used feature of spaCy—the dependency labels. Then, we discovered a famous NLU tool and concept, NER. We saw how to do named entity extraction, again via examples. We finalized this chapter with a very handy tool for merging and splitting the spans that we calculated in the previous sections.

What's next, then? In the next chapter, we will again be discovering a spaCy feature that you'll be using every day in your NLP application code—spaCy's Matcher class. We don't want to give a spoiler on this beautiful subject, so let's go onto our journey...
