Building vocabulary from customer reviews

You're part of a product analytics team at TechZone, a consumer electronics company. You've received a small batch of customer reviews for a new gadget. To analyze the reviews, you'll first preprocess the text and build a vocabulary, a list of unique words that defines the features used to represent each review as numerical data.

A preprocess() function is pre-loaded for you. It lowercases the text, tokenizes it, and removes punctuation.

Instructions

100 XP

Preprocess each review in the dataset using the preprocess() function.
Fit the vectorizer on the preprocessed reviews.
Print the resulting vocabulary.
