Now it is time to take everything we learned and create a real-world application in Cascading. We will use a practical case study, which could be easily adapted to a functional component of a larger system within the reader's organization. This case study uses techniques of text analytics (TA) and natural language processing (NLP). We will start with a brief introduction to the basic concepts and show you how to design and develop a domain-specific Cascading project. The reader will utilize all the knowledge acquired in the previous chapters and learn how to apply it to a specific situation.
