Filtering spam e-mail on a global scale
Geoff Hulten, John Thomas Goodman, Robert Rounthwaite · 2004
In this paper we analyze a very large junk e-mail corpus which was generated by a hundred thousand volunteer users of the Hotmail e-mail service. We describe how the corpus is being collected, and analyze: the geographic origins of the e-mail who the e-mail is targeting and what the e-mail is selling.
