Well, what natural language processing that we use does is it actually goes in and identifies what's the thing that this it actually about. So, it's keeping track as it reads through and says, "Okay, I recognize that there a few things "that we're talking about here, "here are some ideas that are very similar." And it pulls all that together and says… "Okay, at the end, I think that this was really "about these three or four topics. "Like, that's what I'm going to put in front of you "and say this is what this piece "of content was actually about." And, so that's what we use the natural language processing for.
