Abstract/Abridgement


A feedback loop system and method that
facilitates classifyin
g items in connection with
spam prevention in server and/or client
-
based
architectures is disclosed. The invention makes
use of a machine
-
learning approach and is
applied to spam filters. In particular, the system
randomly samples incoming email messages s
o
that examples of both legitimate and junk/spam
mail is obtained to generate sets of training data.
Users who are identified as spam
-
fighters are
asked to vote on whether a selection of their
incoming email messages is individually either
legitimate or ju
nk email. A database stores the
properties for each mail and voting transaction
such as user information, message properties
and content summary, and polling results for
each message, to generate training data for
machine learning systems. The machine lear
ning
systems facilitate creating improved spam filter(s)
that are trained to recognise both legitimate mail
and spam mail and to distinguish between them.
