man Lingua::Stem::It () - Porter's stemming algorithm for Italian

NAME

Lingua::Stem::It - Porter's stemming algorithm for Italian

SYNOPSIS

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


    my $stem = Lingua::Stem::It::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/italian/stemmer.html

The code is carefully crafted to work in conjunction with the Lingua::Stem module by Benjamin Franz, from which I've also borrowed some functionalities (caching and exception list).

METHODS

stem({ -words => \@words, -locale => 'it', -exceptions => \%exceptions });
Stems a list of passed words. Returns an anonymous list reference to the stemmed words. Example: 
  my $stemmed_words = Lingua::Stem::It::stem({ -words => \@words,
                                              -locale => 'it',
                                          -exceptions => \%exceptions,
                          });
Stems a single word and returns the stem directly. Example: 
  my $stem = Lingua::Stem::It::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.
