Introduction to Natural Language Processing

Overview

Build a practical foundation in natural language processing using Python. Learn to explore, preprocess, vectorize, and classify text data with common machine learning techniques.

What you'll learn

  • Explore text datasets using Python and pandas
  • Clean and preprocess raw text for NLP workflows
  • Apply tokenization, stopword removal, stemming, and lowercasing
  • Convert text into numerical features with TF-IDF vectorization
  • Train text classifiers using Naive Bayes and logistic regression
  • Evaluate classification model performance using standard metrics

Advantages and disadvantages

Advantages

  • University courses you can audit for free, with lectures, readings and practice quizzes.
  • A verified certificate from the university if you pay for it.
  • Self-paced: start any time.

Disadvantages

  • Graded assignments and the certificate need the paid track.
  • Audit access can expire a few weeks after the course ends.
  • Learning is free, but the certificate costs money.
  • Some parts (graded work, certificate) are paid.

Some points apply to every course of this kind; see how we rank.

Free to audit

  • Free: Choose "Audit this course" when you enrol: lectures, readings and practice are free.
