What triggers a fallback intent in chatbot logic?

A fallback intent is specifically designed to handle situations where the chatbot cannot recognize the user's intent. When users ask questions or make requests that the chatbot has not been programmed to understand or respond to, the fallback intent is triggered. This typically occurs when there is no matching intent found in the chatbot's training data for the user's input, indicating that the bot cannot adequately process or respond to the request.

In contrast, when user requests are processed successfully or when all intents are recognized, there is no need for a fallback intent to be activated. These situations indicate that the chatbot is functioning as intended, handling user queries appropriately based on its programmed intents. Therefore, the correct identification of a fallback intent being triggered by unrecognized user intent highlights its role as a safety net for interactions that fall outside the scope of the chatbot's knowledge or capabilities.
