It's just a general query, no big thing. I'm just curious.
I've noticed it a lot of times, but today when I was asking a question regarding adding transparency to windows and dialog boxes, mechanism suggested the Unity tag.
The suggested tags were LibreOffice, Firefox, and Unity. The former two were suggested because I made mention of them. But I never mentioned Unity. Of course the tag suggested was totally appropriate, as the question is related to Unity framework.
So I was just wondering how does the mechanism get it that I'm talking about Unity framework when I never make a mention of it?
Does it check for other words, like window or dialog, to suggest Unity?
