My recent article on spam filtering led
reader Lee Williams to send me this message. - A slight variant on your suggestion is based in AI, and it's
called bayesian classification. Rather than having the user
explain to the machine every keyword it wants to flag, the
bayesian classifier simply assigns probabilities to each (word,
phrase) based on what class you put the email in. Then, when it
sees another email, it is able to use these probabilities to
estimate the class it belongs in. It's actually a lot simpler than
having the enduser manually create these filters.
Paul Graham discusses this in his "plan
for spam".
The key element in both solutions is that they are completely
customizable. The existence of individual filters would not
necessarily eliminate 100% of spam to each person, but in the
aggregate it would mean that each email reaches considerably fewer
people, thereby hopefully making it at least somewhat less
cost-effective.
That article is good reading. I think it would be something I would
definitely try. An email client with such filtering would be a great
hit, in my opinion. [Editor's note: Apple's Mail client in
OS X 10.2 includes a Bayesian filter. I've been using it for
over a month and am still training it. dk] I wonder if a combination of the traditional manual filtering and
this would be even better. The manual filtering would allow you to
set a rule for specific phrase or person (say your ex for example)
which gives a 100% probability of being filtered. One interesting point related to your statement about the email
reaching fewer people - which he doesn't make either - is that if a
user actually wanted to receive these emails - after all, someone
must be responding to them - they'd like this filter, too, because
they'd sort the spam they like into the "keep" folder. Contrary to Graham's hypothesis, spam need not end. It would
become highly targeted at those people most likely to respond to it.
The rest of us would ignore it. If everyone had such filters, the
things you're most interested in would be the only things that would
get through. Everyone would like this type of filtering. Haters of spam,
responders of spam, and senders of spam. Now for an even spookier thought - apply the same technology to a
TiVo with voice recognition and filter your TV commercials the same
way.
