Yeah, from the video (videos for text? Really?) you have some categories, but the point is what is the available space of categories?
Do you specify tags you want to filter by? For example, if I wanted to do (random suggestion) SMT IC package identification, how would I do that?

From the sound of it, right now, it sounds like you review the requested categories, and manually/semi-manually generate each specific network?

I'm basically in a position where it'd be much more valuable to me to have a thing I can point at a directory and have it tell me what it found then something I have to say "sort into these categories".
In general, there's very few cases where I have a dataset where I want to filter by a specific content, and don't already have that metadata. Content discovery would be much more useful.
