NAME

Lingua::Stem::Da - Stemming algorithm for Danish

SYNOPSIS

use Lingua::Stem::Da;
my $stems   = Lingua::Stem::Da::stem({ -words => $word_list_reference,
                                      -locale => 'da',
                                  -exceptions => $exceptions_hash,
                                 });

DESCRIPTION

This routine applies a stemming slgorithm to a passed anon array of Danish words, returning the stemmed words as an anon array.

It is a 'convienence' wrapper for 'Lingua::Stem::Snowball::Da' that provides a standardized interface and caching.

1.00 2003.04.05 - Initial release

METHODS

stem({ -words => \@words, -locale => 'da', -exceptions => \%exceptions });

Stems a list of passed words using the rules of Danish. Returns an anonymous array reference to the stemmed words.

Example:

my $stemmed_words = Lingua::Stem::Da::stem({ -words => \@words,
                                            -locale => 'da',
                                        -exceptions => \%exceptions,
                        });

stem_caching({ -level => 0|1|2 });

Sets the level of stem caching.

'0' means 'no caching'. This is the default level.

'1' means 'cache per run'. This caches stemming results during a single call to 'stem'.

'2' means 'cache indefinitely'. This caches stemming results until either the process exits or the 'clear_stem_cache' method is called.

clear_stem_cache;

Clears the cache of stemmed words
