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

You have completed an exhaustive chapter about a very hot topic in NLP. Congratulations! In this chapter, you started by learning what sort of models transformers are and what transfer learning is. Then, you learned about the commonly used Transformer architecture, BERT. You learned the architecture details and the specific input format, as well as the BERT Tokenizer and WordPiece algorithm.

Next, you became familiar with BERT code by using the popular HuggingFace Transformers library. You practiced fine-tuning BERT on a custom dataset for a sentiment analysis task with TensorFlow and Keras. You also practiced using pre-trained HuggingFace pipelines for a variety of NLP tasks, such as text classification and question answering. Finally, you explored the spaCy and Transformers integration of the new spaCy release, spaCy v3.0.

By the end of this chapter, you had completed the statistical NLP sections of this book. Now you're ready to put everything you learned together...
