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.

Sentiment analysis with spaCy

In this section, we'll work on a real-world dataset and train spaCy's TextCategorizer on this dataset. We'll be working on the Amazon Fine Food Reviews dataset (https://www.kaggle.com/snap/amazon-fine-food-reviews) from Kaggle in this chapter. The original dataset is huge, with 100,000 rows. We sampled 4,000 rows. This dataset contains customer reviews about fine food sold on Amazon. Reviews include user and product information, user rating, and text.

You can download the dataset from the book's GitHub repository. Type the following command into your terminal:

wget  https://github.com/PacktPublishing/Mastering-spaCy/blob/main/Chapter08/data/Reviews.zip

Alternatively, you can click on the URL in the preceding command and the download will start. You can unzip the zip file with the following:
