NAME

Lingua::Stem::De - Stemming algorithm for German

SYNOPSIS

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

DESCRIPTION

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

It is a 'convienence' wrapper for 'Text::German' that provides a standardized interface and caching.

METHODS

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

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

Example:

  my $stemmed_words = Lingua::Stem::De::stem({ -words => \@words,
                                              -locale => 'de',
                                          -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
