file from a module distribution so that people browsing the archive
can use it to get an idea of the module's uses. It is usually a good idea
to provide version information here so that people can decide whether
fixes for the module are worth downloading.
INSTALLATION
To install this module, run the following commands:
perl Makefile.PL
make
make test
make install
Alternatively, to install with Module::Build, you can use the following commands:
perl Build.PL
./Build
./Build test
./Build install

our $VERSION = '0.02';
=head1 SYNOPSIS
use AI::CBR::Sim qw(sim_eq ...);
use AI::CBR::Case;
use AI::CBR::Retrieval;
my $case = AI::CBR::Case->new(...);
my $r = AI::CBR::Retrieval->new($case, \@case_base);
...
=head1 DESCRIPTION
Framework for Case-Based Reasoning in Perl.
For an overview, please see my slides from YAPC::EU 2009.
In brief, you need to specifiy an L<AI::CBR::Case>
with the help of similarity functions from L<AI::CBR::Sim>.
Then you can find similar cases from a case-base
lib/AI/CBR/Case/Compound.pm view on Meta::CPAN
AI::CBR::Case::Compound - compound case definition and representation
=head1 SYNOPSIS
Define and initialise a compound (or object-oriented) case.
This is a case consisting of multiple object definitions related in some way.
In a productive system, you will want to encapsulate this.
use AI::CBR::Case::Compound;
use AI::CBR::Sim qw(sim_eq sim_dist);
# assume we sell travels with flight and hotel
# shortcut one-time generated case
my $case = AI::CBR::Case::Compound->new(
# flight object
{
flight_start => { value => 'FRA', sim => \&sim_eq },
flight_target => { value => 'LIS', sim => \&sim_eq },
price => { value => 300, sim => \&sim_dist, param => 200 },
},
# hotel object
{
stars => { value => 3, sim => \&sim_dist, param => 2 },
rate => { value => 60, sim => \&sim_dist, param => 200 },
},
);
...
=head1 METHODS
=head2 new
Creates a new compound case specification.
Pass a list of hash references as argument.
Each hash reference is the same specification as passed to L<AI::CBR::Case>.
=cut
sub new {
my ($class, @definitions) = @_;
# set default weights if unspecified
foreach my $attributes (@definitions) {
foreach (keys %$attributes) {
$attributes->{$_}->{weight} = $DEFAULT_WEIGHT unless defined $attributes->{$_}->{weight};
}
}
my $self = \@definitions;
bless $self, $class;
return $self;
}
=head2 set_values
Pass a flat hash of attribute keys and values.
This will overwrite existing values, and can thus be used as a faster method
for generating new cases with the same specification.
Notice that keys in the different specifications of the compound object may not have the same name!
=cut
sub set_values {
my ($self, %values) = @_;
foreach my $spec (@$self) {
foreach (keys %$spec) {
$spec->{$_}->{value} = $values{$_};
}
}
}
=head1 SEE ALSO
See L<AI::CBR> for an overview of the framework.
