identify type of document (receipt, card, bill)

Hello-
When I use scansnap cloud, the software automagically determines (with very good accuracy) that the document is a receipt, or a business card, etc. The problem is that I can't retroactively do that with the other many documents that I have.
I looked though the various criteria and didn't see anything directly addressing that sort of categorization. Do most people just use the document dimensions (page width and length) or use other means to achieve that?
I did search for "recognize type" "receipt" "page width" and several others, but didn't have any luck. Sorry if this is a rehash.
Thanks.
