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.

Summary

Congratulations! You have made it to the end of a very intense chapter!

In this chapter, you learned how to generate a complete semantic parse of utterances. First, you made a discovery on your dataset to get insights about the dataset analytics. Then, you learned to extract entities with two different techniques – with spaCy Matcher and by walking on the dependency tree. Next, you learned different ways of performing intent recognition by analyzing the sentence structure. Finally, you put all the information together to generate a semantic parse.

In the next chapters, we will shift toward more machine learning methods. The next section concerns how to train spaCy NLP pipeline components on your own data. Let's move ahead and customize spaCy for ourselves!
