Q: How deeply does Starting Data Analytics with Generative AI and Python cover spaCy?

Demonstrates a concrete preprocessing function but stops short of explaining spaCy internals or comparing model quality.

As explained in Starting Data Analytics with Generative AI and Python

spaCy is an open-source Python library for industrial-strength natural language processing.

spaCy is a Python library used here for lemmatization: reducing words to their base forms before keyword matching. This can make searches more consistent, but cleaning choices still depend on the dataset and task. section 5.5.5

Lemmatizing Portuguese reviews

Load the Portuguese model, process each review, collect token lemmas, and store the normalized text before searching keywords: nlp = spacy.load("pt_core_news_sm"); doc = nlp(text); lemmatized_words = [token.lemma_ for token in doc]. Inspect the resulting matches rather than assuming preprocessing improves every measure. section 5.5.5

Dedicated libraries can provide more consistent and scalable text analysis than generative AI, especially for specialized vocabulary, ambiguous language, and repeatable detection tasks. section 5.1.3
