NAME
    Lingua::Stem::Patch - Patch stemmers

VERSION
    This document describes Lingua::Stem::Patch v0.01.

SYNOPSIS
        use Lingua::Stem::Patch;

        # create Esperanto stemmer
        $stemmer = Lingua::Stem::Patch->new(language => 'eo');

        # get stem for word
        $stem = $stemmer->stem($word);

        # get list of stems for list of words
        @stems = $stemmer->stem(@words);

DESCRIPTION
    This module contains a collection of stemmers for multiple languages
    using the Patch stemming algorithms. The languages currently implemented
    are Esperanto and Ido.

    This is a new project under active development and the current stemming
    algorithms are likely to change.

  Attributes
    language
        The following language codes are currently supported.

            ������������������������������������������������������
            ��� Esperanto ��� eo ���
            ��� Ido       ��� io ���
            ������������������������������������������������������

        They are in the two-letter ISO 639-1 format and are case-insensitive
        but are always returned in lowercase when requested.

            # instantiate a stemmer object
            $stemmer = Lingua::Stem::Patch->new(language => $language);

            # get current language
            $language = $stemmer->language;

            # change language
            $stemmer->language($language);

  Methods
    stem
        Accepts a list of words, stems each word, and returns a list of
        stems. The list returned will always have the same number of
        elements in the same order as the list provided. When no stemming
        rules apply to a word, the original word is returned.

            @stems = $stemmer->stem(@words);

            # get the stem for a single word
            $stem = $stemmer->stem($word);

        The words should be provided as character strings and the stems are
        returned as character strings. Byte strings in arbitrary character
        encodings are intentionally not supported.

    languages
        Returns a list of supported two-letter language codes using
        lowercase letters.

            # object method
            @languages = $stemmer->languages;

            # class method
            @languages = Lingua::Stem::Patch->languages;

SEE ALSO
    Lingua::Stem::Any provides a unified interface to any stemmer on CPAN,
    including this module, as well as additional features like
    normalization, casefolding, and in-place stemming.
