Bayesian spam filtering for the masses
Bayesian spam filtering for the masses
10/30/2003 11:59 PMSpam, or unsolicited commercial e-mail, is now a sad part of everyday
life online. Research companies estimate that more than 50% of the
worldwide e-mail traffic is spam. As a result, it's becoming
constantly more difficult and time-consuming to sort out legitimate
e-mails from the deluge of commercial messages we're being flooded
with. But there are ways to fight back. In this series, we'll walk
through choosing and setting up a highly effective package for
screening out spam.

12/02/2003 07:37 AMBayesian anti-spam filters count word-frequency in suspect and compare
the results to profiles of word-frequency in spam and ham. Defeating
this requires that your spam include a lot of natural human prose. So
spammers have started to mine the Gutenberg Project and other sources
of human-generated ASCII and dumping random hunks of literature into
their messages to get around the filters.
Blogger and journalist Clive Thompson found an excerpt from Chapter 20
of The Master Key by Wizard of Oz author L Frank Baum in a message
that had as its subject line "the big unit" (no prizes for guessing
what the rest of it was hawking).

Comment Spam Attack
Comment Spam Attack
02/05/2005 09:12 PMSo, apparently I'm not
the only one that was hit by some bleepity-bleep-bleep spammer
trying to post 400+ comment spams to my blogs. MT-B blocked about 300
of them, moderated 80, and let 4 through. That's pretty decent. The
other 80 all had the same base domain so future attacks will fail for
that one domain. There are also regular expressions in place now that
should moderate the more ... interesting ones.
Your comments may get moderated if you include any terms relating
to animal sex or incest. If so, I'll notice when I check my mail next
and approve/reject it, so don't worry. A little delay is all. Keep
those illegal-in-Alabama discussions going! Woo! 
That said, I'm wondering if going TypeKey-only is the way to go.
Yes, it makes you make an account (boo-hoo) but it keeps things a
little more sane on the management end. If I get two more of these
full-on assaults I'll do it, but not until then. It will alienate the
more lazy amongst you.

I know that 99% of you hate the Typekey registration service and I

cause all of you to have to go register on another site for permission
to post. But until some one builds a better mousetrap we are stuck

aggregator in much of the way you think of it. However, it allows me
to identify keywords or themes that it puts together into phrases
— and then matches up the phrases with like articles. Like a
cross between Google News and Daypop (but that makes it sound much
more complex than it is). If you want to see an "interests" based
summary for me, check out the Phrase Index. I use fairly general
keywords so as not to miss out on the future items. I haven't tried...

Preferably, it should be optimized for server applications and high
performance.

Subconsciously, People may be Bayesian
Subconsciously, People may be Bayesian
01/22/2004 02:48 AM DAVID LEONHARDT writes in a NY Times article about people playing
the odds of everyday life with Bayesian Analysis. He describes new
research, recently published in Nature, "which stands out because it
offers a detailed window into how the Bayesian thought process works,
showing the point when uncertainty becomes great enough to give past
experience an edge over current observation." Bayesian Analysis, among
researchers, is "the combining of new information with conventional
wisdom." I do agree about their reliance on past observations, but I
believe that they have underestimated the role of future orientation
in the whole mix of decision making.

Working with Bayesian categorizers
Working with Bayesian categorizers
12/02/2003 01:38 AM
There's been some discussion in the blog world about using a Bayesian
categorizer to enable a person to discriminate along various
interest/non-interest axes. I took a run at this recently and,
although my experiments haven't been wildly successful, I want to
report them because I think the idea may have merit. [Full story: O'Reilly
Network: Working with Bayesian Categorizers]
This month's O'Reilly Network column was a struggle because
categorization itself is a struggle. I remain convinced that the
automated classifiers that are doing such a good job beating back the
tide of spam will also turn out to be more generally useful. But
finding the right synergy between an automated assistant and a human
overseer is a subtle and tricky thing.
