First, you learned how to create an in-memory knowledge base for retrieving information that can be used to answer questions. Second, you were introduced to the working principles of knowledge base actions and learned how to configure NLU and dialogue management systems so that user requests can trigger knowledge base actions. Third, you learned how to modify knowledge base actions to customize them to your business and how to create a knowledge base by using your own code. Finally, we also built a knowledge-based music query chatbot, step by step, to help you understand those concepts better.

In the next chapter, we will discuss entity roles and groups for complex Named Entity Recognition (NER).
