Don't take it bad, but I find this need to name, or rename, or find names for participles quite obsessional
I may have missed something, so I looked for in Google and I found this quotation :
...this source of ambient data can help provide relevant key words and leads that may have previously been
unknown.

This was just to try to understand what the point was, but it's late here (11 PM), and I feel maybe I'm too tired to understand where it leads...
So this was my modest contribution: trying to find an example in a real context (or a cotext, or whatever). Now, I understand what it means, I know how the sentence works, what else do I need?...
