NAME

Lingua::ZH::MMSEG Mandarin Chinese segmentation

SYNOPSIS

    #!/usr/bin/perl
    use utf8;
    use Lingua::ZH::MMSEG;

    my $seg = Lingua::ZH::MMSEG->new();

    my $zh_string="現代漢語的複合動詞可分三個結構語意關係來探討";

    my @phrases = $seg->mmseg($zh_string);
    # use MMSEG algorithm

    my @phrases = $seg->fmm($zh_string);
    # use Forward Maximum Matching algorithm

DESCRIPTION

A problem in computational analysis of Chinese text is that there are no word boundaries in conventionally printed text. Since the word is such a fundamental linguistic unit, it is necessary to identify words in Chinese text so that higher-level analyses can be performed.

Lingua::ZH::MMSEG implements MMSEG original developed by Chih-Hao-Tsai. The whole module is rewritten in pure Perl, and the phrase library is 新酷音 forked from OpenFoundry.

INSTALL

If you are familier with CPAN, just simply

    cpanm Lingua::ZH::MMSEG

If you are not,

    make 
    sudo make install

USAGE

Since this module has no dependency at all, you just simply create a new perl script as shown in SYNOPSIS.

METHODS

new

    my $seg = Lingua::ZH::MMSEG->new()

Initialize phrase dictionary. Currently it is not allowed to add new phrase into the dictionary.

mmseg

    my @phrases = $seg->mmseg($zh_string);

Use MMSEG algorithm to generate segmented chinese phrases.

fmm

    my @phrases = $seg->fmm($zh_string);

Use forward maximum matching algorithm to generate segmented chinese phrases. It has lower complexity compare to mmseg, but it cannot solve phrase ambiguities.
