机器人无法回答时的表现及如何访问此类问题优化QnA机器人

Hey there, let's break this down clearly for you:

1. What happens when the bot can't answer a question? #

As you've observed, when your bot doesn't find a matching answer in its knowledge base, it fires off a pre-set fallback response:

I don’t have an answer for that. Try typing MENU to go back to the main menu

This is totally standard behavior, especially when your knowledge base is still in the learning phase. It’s the bot’s way of being transparent with users—letting them know it can’t assist with that specific query right now, while guiding them back to available, supported actions.

2. How to access unanswered questions to optimize your bot? #

To pull up those unaddressed queries and refine your bot’s knowledge base, follow these straightforward steps (most QnA bot platforms use similar workflows):

• Log into your bot’s administrative dashboard or the QnA management portal you’re using
• Navigate to a section labeled Analytics, Logs, or User Queries—this is where all user interactions are tracked and stored
• Use the filtering tools to narrow down results to queries that triggered the fallback response (look for tags like "Unanswered", "Fallback Activated", or filter by the exact fallback message text)
• You can usually view these questions directly in the dashboard, or export them as a CSV/Excel file to analyze patterns or prioritize updates in bulk
• Once you have the list, focus on adding answers to the most frequent unanswered questions, or tweak existing knowledge base entries to cover related, similar queries

By regularly reviewing these unanswered queries, you’ll steadily expand your bot’s capabilities and make it more helpful for users over time.
