For Text Mining and Analytics, we have two good courses one on coursera and other on on eDX.
Text Mining and Analytics (Coursera): This course covers the major techniques for mining and analyzing text data to discover interesting patterns, extract useful knowledge, and support decision making, with an emphasis on statistical approaches that can be generally applied to arbitrary text data in any natural language with no or minimum human effort.
- Text Mining and Analytics (eDX): This course describes a range of business opportunities and solutions centered around the use of text and it also identify sources of competitive intelligence, in text, and provide solutions for parsing and storing incoming knowledge. It uses real-world case studies, the course provides examples of the most useful statistical and machine learning techniques for handling text, semantic, and social data. We then describe how and what you can infer from the data, and discuss useful techniques for visualizing and communicating the results to decision-makers.
Addition to above courses, you can also look at below articles:
- Clean text data and build models on it
