NAME
KinoSearch1::Analysis::Stopalizer - suppress a "stoplist" of common words
SYNOPSIS
my $stopalizer = KinoSearch1::Analysis::Stopalizer->new( language => 'fr', ); my $polyanalyzer = KinoSearch1::Analysis::PolyAnalyzer->new( analyzers => [ $lc_normalizer, $tokenizer, $stopalizer, $stemmer ], );
DESCRIPTION
A "stoplist" is collection of "stopwords": words which are common enough to be of little value when determining search results. For example, so many documents in English contain "the", "if", and "maybe" that it may improve both performance and relevance to block them.
# before @token_texts = ('i', 'am', 'the', 'walrus'); # after @token_texts = ('', '', '', 'walrus');
CONSTRUCTOR
new
my $stopalizer = KinoSearch1::Analysis::Stopalizer->new( language => 'de', ); # or... my $stopalizer = KinoSearch1::Analysis::Stopalizer->new( stoplist => \%stoplist, );
new() takes two possible parameters,
language
andstoplist
. Ifstoplist
is supplied, it will be used, overriding the behavior indicated by the value oflanguage
.stoplist - must be a hashref, with stopwords as the keys of the hash and values set to 1.
language - must be the ISO code for a language. Loads a default stoplist supplied by Lingua::StopWords.
