What this course is about

Text data is emerging as a critical source of information for businesses and organizations. With the growing use of natural language processing (NLP) techniques, text data provides valuable insights and helps us make informed decisions. However, raw text data is often unstructured and noisy, making text preprocessing a crucial step in the NLP pipeline.

Text preprocessing entails cleaning and transforming raw text data into a format suitable for analysis. It involves techniques like handling irrelevant information, removing noise, and converting text into a structured format that can be used for various NLP tasks. By performing text preprocessing, we can enhance the accuracy and efficiency of NLP models, which rely heavily on the quality of input data.

What we’ll learn

This course is designed to provide a comprehensive understanding of text preprocessing and its application in developing data solutions. By the end of the course, we’ll be able to:

  • Understand the significance of text preprocessing in natural language processing and its impact on text analysis tasks.

  • Apply various text-cleaning techniques, including the use of regular expressions, lowercase and uppercase transformations, and stopword removal.

  • Evaluate the effectiveness of text normalization techniques, such as stemming and lemmatization, on improving text analysis performance.

  • Design and implement different text representation models, such as bag-of-words and TF-IDF, to capture important information from text data.

  • Apply various text preprocessing techniques and models in a real-world application, such as text classification of customer reviews, to gain practical experience and evaluate their effectiveness.

The audience

If you’re a data professional who wants to learn how to transform and prepare text data for analysis, or if you’re interested in learning Python for text preprocessing and aspire to become a data analyst, data scientist, data engineer, or machine learning engineer, this course is perfect for you. No prior knowledge of text preprocessing is necessary, but a basic understanding of Python programming is recommended.
