You have set up a certain number of topics in FAQ or in actions and your chatbot responds that it did not understand?

First of all, you have to understand how the chatbot works.

1. When a query is typed, the algorithm calculates the probability of finding a parameterized intent (score /1)
2. If the algorithm finds an intent with a score> 0.5 (default level) then it executes the parameterized logic
3. If it finds an intent with a score< 0.5 or no intention at all so he says he didn’t understand
