NAME Lingua::Stem::Ru - Porter's stemming algorithm for Russian 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 (I hope :-) as described in: http://snowball.tartarus.org/russian/stemmer.html The code is carefully crafted to work in conjunction with the Lingua::Stem module by Benjamin Franz. This stemmer is also based on the work of Aldo Capini Lingua::Stem::It. 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.
