thank you for the answers.

unfortunately, we don't have resources for researching about finite state transducers (which we have already heard about).

we are trying to find a solution. we have already posted a question similar to this one (http://www.perlmonks.org/?node_id=658691), and the user GrandFather has given a very interesting partial solution (which uses a recursive search to find all matching combinations of cowboycatdog, based on the lexicon cowboy, cow, boy, cat, at, do, dog):

use strict;
use warnings;

my $target = "cowboycatdog";
my @partsList = qw(cowboy cow boy cat at do dog);
my %partsLu;

++$partsLu{$_} for @partsList;

search ($target, {%partsLu}, []);

sub search {
    my ($target, $partsLu, $used) = @_;

    unless (length $target) {
        print join ("-", @$used), "\n";
        return;
    }

    for my $part (keys %$partsLu) {
        next unless 0 == index $target, $part;

        my $remainder = substr $target, length $part;

        delete $partsLu->{$part} unless --$partsLu->{$part};
        search ($remainder, {%$partsLu}, [@$used, $part]);
    }
}

which prints:

cow-boy-cat-dog

cowboy-cat-dog

the only limitation with this method regarding this problem is that it doesn't consider that the words may have been joined together by phonetic rules (for example, cowboycaddog).

so, would it be a good idea trying to adapt the above code, or creating one that uses a similar method? any suggestions?
