The "or" doesn't make any sense to me. Theres absolutely no reason at all to have a tag with two completely unrelated meanings.
no not many questions using the tag for the second "data-extraction" meaning (maybe this, which looks off-topic and confusing) and I'm not sure that has all that much to do with graphic design anyway. There are a few questions that are talking about using CC's "Extract Assets" feature, which I don't think fits in either description.
So, if we're going to do anything with it: remove the "or..." from the description and make it a synonym of background-removal and retag existing questions. Or better yet...
