NAME¶

Lingua::Stem::Fr - Perl French Stemming

SYNOPSIS¶

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

DESCRIPTION¶

This module use the a modified version of the Porter Stemming Algorithm to return a stemmed words.

The algorithm is implemented as described in:

http://snowball.tartarus.org/french/stemmer.html

with some improvement.

The code is carefully crafted to work in conjunction with the Lingua::Stem module by Benjamin Franz. This french version is based too, on the work of Aldo Calpini (Italian Version)

METHODS¶

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

Example:

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

stem_word( $word );

Stems a single word and returns the stem directly.

Example:

    my $stem = Lingua::Stem::Fr::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
