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

The algorithm is implemented exactly (I hope :-) as described in:

    http://snowball.tartarus.org/algorithms/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,
                          });
    

stem_word( $word );

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
