In the field of data science, the ability to extract key information from large volumes of text, clean messy data containing strings, and identify patterns to uncover valuable words is crucial. These tasks fall under the umbrella of text mining and serve as a vital preliminary step before applying machine learning algorithms. This comprehensive course aims to equip you with a deep understanding of essential concepts related to string manipulation and regular expressions. Throughout the program, you will gain proficiency in various techniques such as string splitting, joining, interpolation, as well as detecting, extracting, replacing, and matching strings using regular expressions. To enhance your learning experience, you will engage with diverse datasets encompassing movie reviews, streamed tweets, and raw text scraped from the web. These datasets will enable you to analyze opinions, sentiments, and other valuable insights. By the end of this course, you will have honed your skills in text mining, empowering you to effectively extract and manipulate textual data for further analysis and machine learning applications.
