Well charts is a good addon but just wanted to understand how they are able to do this ... i mean Machine Learning part , for example if somebody asks "Show me sales of X product in last year" , from machine learning perspective how this gets interpreted in actual SQL query ..

Presumably some ad engineers got sick of producing arbitrary customer reports, took the corpus of all customer requests, and tied it to the sheets that generated those reports. And a ton of glue code to make it all work.

I wonder if it's actually machine learning or if they just implemented a query language that tries to guess what you mean.

The definition of machine learning that I use is: an algorithm which improves its performance through experience.

So, if charts doesn't get better the more you use it, it's not machine learning.

If I had to guess I'd say the machine learning part is analyzing a sentence ("Show me a line graph for x, y, and z") and determining what exactly they want to see.

Seems similar to what Wolfram Alpha does, but restricted to a smaller data set.
