NAME

Lucy::Analysis::SnowballStemmer - Reduce related words to a shared root.

SYNOPSIS

    my $stemmer = Lucy::Analysis::SnowballStemmer->new( language => 'es' );
    
    my $polyanalyzer = Lucy::Analysis::PolyAnalyzer->new(
        analyzers => [ $tokenizer, $normalizer, $stemmer ],
    );

This class is a wrapper around the Snowball stemming library, so it supports the same languages.

DESCRIPTION

SnowballStemmer is an Analyzer which reduces related words to a root form (using the “Snowball” stemming library). For instance, “horse”, “horses”, and “horsing” all become “hors” – so that a search for ‘horse’ will also match documents containing ‘horses’ and ‘horsing’.

CONSTRUCTORS

new

    my $stemmer = Lucy::Analysis::SnowballStemmer->new( language => 'es' );

Create a new SnowballStemmer.

  • language - A two-letter ISO code identifying a language supported by Snowball.

METHODS

transform

    my $inversion = $snowball_stemmer->transform($inversion);

Take a single Inversion as input and returns an Inversion, either the same one (presumably transformed in some way), or a new one.

  • inversion - An inversion.
