Let's analyse and classify my mail. Whenever I receive a letter, I open it, scan it, OCR it, and throw it into a folder on my computer. I will give you one scanned letter at a time, and you will extract a few basic facts from each letter: Date: yyyy-mm-dd Sender: just the name of a person or organization Category: bank, credit card, insurance, personal, junk, medical, unknown, etc. Intent: a one-line basic summary of why they sent it to me
