This module implements the classic "Naive Bayes" machine learning algorithm. It is a well-studied probabilistic algorithm often used in automatic text categorization. Compared to other algorithms (kNN, SVM, Decision Trees), it's pretty fast and reasonably competitive in the quality of its results. A paper by Fabrizio Sebastiani provides a really good introduction to text categorization: http://faure.iei.pi.cnr.it/~fabrizio/Publications/ACMCS02.pdf

Following the release of CPAN::Mini, the CPAN::Mini::Inject module was created to add additional distributions into a minicpan mirror. While it was created for use with a minicpan mirror, similar functionality can be reused in other situations. CPAN::Inject replicates the basics of this functionality. Specifically, it takes an arbitrary tarball and adds it to the CPAN sources directory for a particular author, and then add the new file to the CHECKSUMS file.

Autoconf is an extensible package of m4 macros that produce shell scripts to automatically configure software source code packages. These scripts can adapt the packages to many kinds of UNIX-like systems without manual user intervention. Autoconf creates a configuration script for a package from a template file that lists the operating system features that the package can use, in the form of m4 macro calls.

bcompiler enables you to encode your scripts in phpbytecode, enabling you to protect the source code. bcompiler could be used in the following situations - to create a exe file of a PHP-GTK application (in conjunction with other software) - to create closed source libraries - to provide clients with time expired software (prior to payment) - to deliver close source applications - for use on embedded systems, where disk space is a priority.

This Perl module is a direct translation of Steffen Beyer's excellent Date::Calc module to use Perl only instead of a combination of Perl and C. This package consists of a Perl module for all kinds of date calculations based on the Gregorian calendar (the one used in all western countries today), thereby complying with all relevant norms and standards: ISO/R 2015-1971, DIN 1355 and, to some extent, ISO 8601 (where applicable).

ptkdb is a debugger for perl that uses Perl/Tk for a user interface. Features include: Hot Variable Inspection Breakpoint Control Panel Expression List Subroutine Tree To debug a script using ptkdb invoke perl like this: perl -d:ptkdb myscript.pl ptkdb can easily be used to debug CGI scripts if your web server box is capable of running Perl/Tk applications. Just change the shebang line of your scripts to: #! /usr/bin/perl -w -d:ptkdb

"Joseki" is a japanese term from the game Go and means "a formulaic sequence of moves which is established for giving equal outcomes to both players", but it has come into general use to describe any fixed form of behaviour. Dist::Joseki offers you tools that help you in developing Perl module distributions if you stick to a certain formulaic style of structuring your distributions.

This module can build the C portions of Perl modules by invoking the appropriate compilers and linkers in a cross-platform manner. It was motivated by the Module::Build project, but may be useful for other purposes as well. However, it is not intended as a general cross-platform interface to all your C building needs. That would have been a much more ambitious goal!

This module can be used to determine the mime type of a file. It tries to implement the freedesktop specification for a shared MIME database. For this module shared-mime-info-spec 0.12 was used. This package only uses the globs file. No real magic checking is used. The File::MimeInfo::Magic package is provided for magic typing. If you want to determine the mimetype of data in a memory buffer you should use File::MimeInfo::Magic in combination with IO::Scalar.

A Hash::AsObject is a blessed hash that provides read-write access to its elements using accessors. (Actually, they're both accessors and mutators.) It's designed to act as much like a plain hash as possible; this means, for example, that you can use methods like DESTROY and if the Hash::AsObject has an element with that name, it'll get or set it.
