Learn the foundations of Natural Language Processing (NLP) with Python in this beginner-friendly crash course. This tutorial covers key text processing techniques including tokenization, regular expressions, and text cleaning. Whether you’re new to NLP or revisiting core concepts, this session provides a practical starting point for working with textual data in Python.
In this tutorial, you’ll learn:
How to tokenize text using Python’s built-in tools, NLTK, and spaCy
How to apply regular expressions for pattern detection in text
How to preprocess text by normalizing, cleaning, and simplifying language
How to prepare text data for downstream NLP and machine learning tasks
🧠 What You’ll Learn in This Course:
Introduction to NLP: Understand what Natural Language Processing is, why it’s useful, and where it’s applied in the real world
Tokenization Techniques: Learn multiple approaches for breaking text into smaller units, including word and sentence tokenization
Regular Expressions: Use Python’s re module to extract text patterns such as hashtags, dates, and emails
Text Preprocessing Steps: Perform basic text normalization, remove stopwords, apply stemming and lemmatization, and explore how tools like spaCy streamline these steps
