Key Highlights Of This Natural Language Processing Course

What You Will Learn

Basic Lexical Processing

Learn basic lexical processing and preprocessing for text analytics. Apply it to machine learning, language models, chatbots, and sentiment analysis. Build a spam-ham detector with an unclean text corpus.

  • Tokenisation
    Break down large texts into individual words or tokens—an essential step that allows machine learning models to interpret and analyze text effectively.

  • Stop words removal
    Remove common yet uninformative words like “the,” “is,” or “and” to enhance the quality of text data and improve model accuracy.

  • Stemming
    Learn how to reduce words to their base or root form by chopping off suffixes—helpful in normalizing textual data for better analysis.

  • Lemmatization
    Unlike stemming, lemmatization considers the context to convert words to their meaningful base forms, ensuring more accurate and readable preprocessing.

  • Bag-of-words model
    Understand how to represent text as numerical vectors based on word frequency, forming the foundation for traditional machine learning algorithms in NLP.


  • TF-IDF model
    Learn to weigh terms based on their importance across documents using Term Frequency–Inverse Document Frequency—crucial for document classification and retrieval tasks

Advanced Lexical Processing

Despite preprocessing, data can have noise like spelling mistakes and informal words (‘lol’, ‘awsum’). You'll learn to identify and correct misspelled words and handle spelling variations from different pronunciations.

  • Phonetic hashing & the Soundex algo
    Explore phonetic algorithms like Soundex that encode words based on pronunciation—ideal for identifying similar-sounding words and resolving inconsistencies in user-generated text.

  • The minimum-edit-distance algorithm
    Understand how this algorithm calculates the least number of operations required to transform one word into another—widely used in spell-check and auto-correct systems.


  • PMI score
    Learn how Pointwise Mutual Information (PMI) measures the association between word pairs in a text—helpful in tasks like synonym detection, word clustering, and topic modeling.
