Hi
WE have worked extensively with the Dialogflow system from Google. Intents and Entities are really important and well done within Dialogflow to control the conversation. We think there are a few underrated pieces of this system.
1) Contexts are like the glue that holds this conversation together. Very Powerful.
2) Session Level Entities enables the Entity to be customized at the session level. So if I want to use an Entity that uses my particular data I can for the duration of the session. This enable a bunch of possibilities.
3) Create Intents and Entities pre-loaded with YOUR data and used the users of the Agent is really the basis for Dynamic Conversations. Specials, Promotions, Pricing, Announcements, Inventory Levels, ….. . All go to make for better experiences for the Customers, Suppliers and Employees.
You should take the time to understand how some of this stuff works.
