Text mining techniques can be applied to create a structured representation of text, making its content more accessible for researchers. Applications of text mining are everywhere: social media, web search, advertising, emails, customer service, healthcare, marketing, etc.</p> <p>This course offers an extensive exploration into text mining with Python. The course has a strong, practical, hands-on focus, and students will gain experience in using text mining and interpreting results using real data from, for example, social sciences and healthcare. Through lectures and practicals, the students will learn the necessary skills to design, implement, and understand their own text mining pipeline.</p> Content content-707024 Sat, 07 Mar 2026 00:53:22 +0100 https://www.uni-bremen.de/data-science-center/trainings-services/trainings-workshops/dsc-2026-03-applied-text-mining-using-python#c707024 <p>The course deals with the following topics:</p> <ul><li>Review the fundamental approaches to text mining;</li><li>Understand and apply current methods for analyzing texts;</li><li>Define a text mining pipeline given a practical data science problem;</li><li>Implement all steps in a text mining pipeline: feature extraction, feature selection, model learning, model evaluation;</li><li>Understand and apply state-of-the-art methods in text mining;</li></ul> <p>The course starts with reviewing basic concepts of text mining and implementing advanced concepts in natural language processing.</p> Content content-707022 Sat, 07 Mar 2026 00:53:22 +0100 https://www.uni-bremen.de/data-science-center/trainings-services/trainings-workshops/dsc-2026-03-applied-text-mining-using-python#c707022 <h5>DAY 1: Introduction to Applied Text Mining</h5> <ul><li><strong>Part 1:</strong><ul><li>What is text mining?</li><li>Text preprocessing</li><li>Vector space model</li><li>Practical</li></ul></li><li><strong>Part 2:</strong><ul><li>Classification basics</li><li>Text classification algorithms</li><li>Evaluating classifiers</li><li>Practical</li></ul></li></ul> <h5>DAY 2: Text Classification and Feature Selection in Text</h5> <ul><li><strong>Part 3:</strong><ul><li>How to do feature selection (FS) for text data?</li><li>Is PCA a FS method for text?</li><li>Other methods?</li><li>Practical</li></ul></li><li><strong>Part 4:</strong><ul><li>What is text clustering?</li><li>What are the applications?</li><li>How to cluster text data?</li><li>Practical<br> </li></ul></li></ul> Content content-707018 Sat, 07 Mar 2026 00:53:22 +0100 https://www.uni-bremen.de/data-science-center/trainings-services/trainings-workshops/dsc-2026-03-applied-text-mining-using-python#c707018 <p>This course is ideal for learners <strong>who are comfortable with Python programming</strong>, wish to acquire skills in text mining approaches, and have a foundational understanding of machine learning.
