Power BI enables natural language in follow-up queries
Asking questions is good! And Microsoft’s Power BI makes it really easy for users to ask questions in plain language when viewing Power BI reports.
Now, Power BI is going a step further, by extending natural language processing to follow-up questions.
The Power BI blog offers some examples of follow-up questions now recognised by Power BI:
Modifications of the original question
Original Question: How many Chicago customers bought green products?
Follow up: What about red products?
or
Original Question: Which Chicago customers bought green products?
Follow up: Show Seattle customers instead
New, but related questions
Original Question: Count the Seattle customers
Follow up: What did they buy last year?
or
Original Question: Which Seattle customers bought discontinued red products?
Follow up: What is the average price of those products?
Augmentations of the original question
Original Question: Count the customers
Follow up: Group by city
or
Original Question: List the products
Follow up: Sort by total sales, descending
You can enable natural language questions in Power BI reports by going to the Buttons menu and clicking Q&A.

Power BI has also added the ability of use the Q&A tool with cloud models that use Row-Level Security.
“This new capability involves security at all layers. In addition to standard prevention of access to restricted data, Q&A refuses to even acknowledge the existence of that data.”
