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.

Transformers and spaCy

spaCy v3.0 was released with great new features and components. The most exciting new feature is undoubtedly transformer-based pipelines. The new transformer-based pipelines bring spaCy's accuracy to the state of the art. Integrating transformers into the spaCy NLP pipeline introduced one more pipeline component called Transformer. This component allows us to use all HuggingFace models with spaCy pipelines. If we recall from Chapter 2, Core Operations with spaCy, this is what the spaCy NLP pipeline looks like without transformers:

With the release of v3.0, v2 style spaCy models are still supported and transformer-based models are introduced. A transformer-based pipeline component looks like the following:

For each supported language, transformer-based models and v2 style models are...
