Summary
In this chapter, we introduced entity roles and entity groups. First, we discussed why we need entity roles and entity groups. Second, we examined how to create NLU training data for entity roles and entity groups. Third, we introduced how to configure NLU and dialogue management systems so that we can use entity roles and entity groups. Finally, we built a ticket and drink booking bot, step by step, to help you understand those concepts better.
In the next chapter, we will discuss how Rasa works and examine how to extend (that is, customize) Rasa's functions.
