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/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

  EXPORT
None by default.
