How does Googles “content extraction” work?
While Google has not released technical details of how the Gmail e-mail “content extraction” and analysis works, the patent (#20040059712) filed with the US Patent and Trademark Office provides some clues. Gmail examines the entire content of the e-mail message including the header and addressing information (see 2.2 for more details) in order to derive the the “concepts” contained in the e-mail. Relevant ads are then placed to the subscriber when the e-mail is displayed. Different ads may be served at different times depending on when the e-mail message is viewed, or re-viewed.
