📛 NAME

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

🚀 Quick Reference

Use Case	Command	Description
Stem multiple words	Lingua::Stem::Ru::stem({ -words => \@words, -locale => 'ru' })	Returns an arrayref of stems
Stem a single word	Lingua::Stem::Ru::stem_word($word)	Returns the stem directly
Enable unlimited caching	Lingua::Stem::Ru::stem_caching({ -level => 2 })	Cache stems indefinitely

📖 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 Lingua::Stem module by Benjamin Franz. This stemmer is also based on the work of Aldo Capini, see Lingua::Stem::It.

🛠️ METHODS

🌱 stem

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

Stems a single word and returns the stem directly.

Example:

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

💾 stem_caching

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.
