NAME

6       Lingua::Stem::It - Porter's stemming algorithm for Italian
7

SYNOPSIS

9           use Lingua::Stem::It;
10           my $stems = Lingua::Stem::It::stem({ -words => $word_list_reference,
11                                                -locale => 'it',
12                                                -exceptions => $exceptions_hash,
13                                             });
14
15           my $stem = Lingua::Stem::It::stem_word( $word );
16

DESCRIPTION

18       This module applies the Porter Stemming Algorithm to its parameters,
19       returning the stemmed words.
20
21       The algorithm is implemented exactly (I hope :-) as described in:
22
23           http://snowball.tartarus.org/algorithms/italian/stemmer.html
24
25       The code is carefully crafted to work in conjunction with the
26       Lingua::Stem module by Benjamin Franz, from which I've also borrowed
27       some functionalities (caching and exception list).
28

METHODS

30       stem({ -words => \@words, -locale => 'it', -exceptions => \%exceptions
31       });
32           Stems a list of passed words. Returns an anonymous list reference
33           to the stemmed words.
34
35           Example:
36
37             my $stemmed_words = Lingua::Stem::It::stem({ -words => \@words,
38                                                          -locale => 'it',
39                                                          -exceptions => \%exceptions,
40                                     });
41
42       stem_word( $word );
43           Stems a single word and returns the stem directly.
44
45           Example:
46
47             my $stem = Lingua::Stem::It::stem_word( $word );
48
49       stem_caching({ -level => 0|1|2 });
50           Sets the level of stem caching.
51
52           '0' means 'no caching'. This is the default level.
53
54           '1' means 'cache per run'. This caches stemming results during a
55           single
56               call to 'stem'.
57
58           '2' means 'cache indefinitely'. This caches stemming results until
59               either the process exits or the 'clear_stem_cache' method is
60           called.
61
62       clear_stem_cache;
63           Clears the cache of stemmed words
64
65   EXPORT
66       None by default.
