Ques 3

What is the difference between intents and entities in Watson Assistant?

Intents represent the user’s goal or purpose in a conversation, while entities are specific details within the user’s input that provide additional context. Intents guide the overall response, and entities refine it.

Example:

In a travel booking bot, the intent could be 'Book Flight', while entities might include 'departure city' and 'destination'.

Ques 15

What is Watson Assistant's disambiguation feature?

The disambiguation feature in Watson Assistant provides a way to handle ambiguous inputs by asking the user clarifying questions. It ensures the user is directed to the correct intent when multiple intents match.

Example:

If a user says 'I need help', Watson Assistant might ask whether they need help with billing or technical support.
