Comprehensive Detailed Explanation
When you develop a custom question answering project (formerly QnA Maker, now part of Azure Cognitive Service for Language - Question Answering), you can configure it for multi-turn conversations.
Follow-up prompts
Used to create multi-turn conversations.
They allow the system to present additional questions to the user after an initial question, guiding the conversation flow.
Example:
User: " Tell me about Azure Storage. "
Bot: " Which type of storage: Blob, File, Queue, or Table? "
These follow-up options are configured using follow-up prompts.
Correct choice for this question.
Active learning
Helps improve the knowledge base by suggesting alternative questions from user queries.
Not related to multi-turn conversation flow.
Alternate questions
Used to add different phrasings for the same question.
Example: "What is Azure Blob Storage?" and "Explain Blob Storage in Azure." This improves recognition but does not enable multi-turn conversations.
Chit-chat
Adds small talk and casual conversation handling (e.g., greetings, jokes).
Not related to multi-turn Q & A about a knowledge base.
The answer: A. Add follow-up prompts
