Filter syslog using Bayesian algorithm

bayeslog - a Bayesian log filter

bayeslog is a Perl script that filters standard syslog-style UNIX log files using Bayes' Theorem (similar to the way many antispam tools filter out unwanted email messages).

For more information, view the documentation included in the script:

$ perldoc ./bayeslog

Note that bayeslog is very much experimental at this stage.

Manifest

• bayeslog

  the filter script

• bayesprint

  a debugging tool to print out the current Bayes model from the storage file.

Installation

1. Install the Algorithm::NaiveBayes module from CPAN.
2. Edit the bayeslog script and change the path to the Perl interpreter and the extra library path if required.
3. Copy the bayeslog script to a directory in your PATH.

Operation

See the integrated documentation or try the --help option.

TODO list

• FIX: Strip out 'UNSURE XX/YY' from training input lines if present (reentered output).
• Refine word weighting and interpretation.
• Improve selection of log records?
• Change keep/discard terminology to something simpler (good/bad? yes/no?)?

Bug reports, suggestions, requests

It's experimental, you want the moon on a stick too? :-)
