NAME

Lingua::Stem::Ru - Porter's stemming algorithm for Russian (KOI8-R only)


SYNOPSIS

    use Lingua::Stem::Ru;
    my $stems = Lingua::Stem::Ru::stem({ -words => $word_list_reference,
                                         -locale => 'ru',
                                         -exceptions => $exceptions_hash,
                                      });
    my $stem = Lingua::Stem::Ru::stem_word( $word );


DESCRIPTION

This module applies the Porter Stemming Algorithm to its parameters, returning the stemmed words.

The algorithm is implemented exactly as described in:

    http://snowball.tartarus.org/algorithms/russian/stemmer.html

The code is carefully crafted to work in conjunction with the the Lingua::Stem manpage module by Benjamin Franz. This stemmer is also based on the work of Aldo Capini, see the Lingua::Stem::It manpage.


METHODS

stem({ -words => \@words, -locale => 'ru', -exceptions => \%exceptions });
Stems a list of passed words. Returns an anonymous list reference to the stemmed words.

Example:

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

stem_word( $word );
Stems a single word and returns the stem directly.

Example:

  my $stem = Lingua::Stem::Ru::stem_word( $word );

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

EXPORT

None by default.
