String::Normal - Just another normal form string transformer.
use String::Normal; my $normalizer = String::Normal->new( type => 'business' ); print $normalizer->transform( 'Jones & Sons Bakeries' ); # bakeri jone son $normalizer = String::Normal->new( type => 'address' ); print $normalizer->transform( '123 Main Street Suite A47' ); # 123 main st $normalizer = String::Normal->new( type => 'phone' ); print $normalizer->transform( '(818) 423-7750' ); # 8184237750 $normalizer = String::Normal->new( type => 'city' ); print $normalizer->transform( 'Los Angeles' ); # los angeles $normalizer = String::Normal->new( type => 'state' ); print $normalizer->transform( 'California' ); # ca $normalizer = String::Normal->new( type => 'zip' ); print $normalizer->transform( '90292' ); # 90292
THIS MODULE IS AN ALPHA RELEASE!
Transform strings into a normal form. Performs tokenization, snowball stemming, stop word removal and complex name compression.
new( %params )
my $normalizer = String::Normal->new( %params );
Constructs object. Accepts the following named parameters:
type
Available types: business, address, phone, city, state, zip and title. Defaults to business.
business
my $normalizer = String::Normal->new( type => 'title' );
various configuration overides
See "TYPE CLASSES" for more information.
transform( $word )
my $scalar = $normalizer->transform( 'Alien 1979 1080p.avi' );
Normalizes word based on given type.
Consider the following values:
Bary & Sons' Bakery Bary's & Sons Bakeries Bary's and Sons' Bakeries
These are business names as potentialy found in business listings. When each of these values is passed to transform() the return value will be "bakeri bari son." This is accomplished by a number of transformation rules, found in the respective Type class.
transform()
Type
String::Normal::Type::Business
Rules for business name listings, such as "Bary's Bakery". Provides business_stem, business_stop and business_compress data overides:
business_stem
business_stop
business_compress
my $normalizer = String::Normal->new( business_stem => '/path/to/stem.txt' );
String::Normal::Type::Address
Rules for business address listings, such as "123 Main Street Suite A". Provides address_stem and address_stop data overides:
address_stem
address_stop
my $normalizer = String::Normal->new( type => 'address', business_stem => '/path/to/stem.txt', );
String::Normal::Type::City
Rules for names of cities.
String::Normal::Type::State
Rules for US and Canadian state codes.
String::Normal::Type::Zip
Rules for US and Canadian zip codes.
String::Normal::Type::Phone
Rules for US area and exchange phone codes. Provides area_codes data overides:
area_codes
my $normalizer = String::Normal->new( type => 'phone', area_codes => '/path/to/codes.txt', );
String::Normal::Type::Title
Rules for movie, film and television show titles. Provides title_stem and title_stop data overides:
title_stem
title_stop
my $normalizer = String::Normal->new( type => 'title', title_stop => '/path/to/stop-words.txt', );
The movitation for such transformation is to identify duplicates when combining multiple digest feeds into a master feed. This transformation (called normalization here) was designed with the need to identify and match duplicate business listings, but can be used to match duplicated from other sources as well, such as movie, film and television show titles.
Each type uses data found in a respective Config class.
Business values are first compressed, then stemmed via Lingua::Stem (with customizations) and finally stop worded.
String::Normal::Config::BusinessStop
Contains stop words to be removed from business names.
String::Normal::Config::BusinessStem
Stem words are transformed into some normal form, business types use Lingua::Stem with some customizations.
String::Normal::Config::BusinessCompress
Compress words are combined into one word. Consider:
Box*Mart Box-Mart Box Mart BoxMart
These are all "compressed" into the value boxmart by specifying the value box-mart in the compression list.
boxmart
box-mart
Address values are first stemmed with a simple substitution and then finally stop worded.
String::Normal::Config::AddressStop
Contains stop words to be removed from addresses.
String::Normal::Config::AddressStem
Transforms into some normal form, but does not use Lingua::Stem.
Title values are stop worded first, then stemmed via Lingua::Stem.
String::Normal::Config::TitleStop
Contains stop words to be removed from titles.
String::Normal::Config::TitleStem
Transforms into some normal form, via Lingua::Stem with no customizations.
String::Normal::Config::State
Valide US and Canadian state codes.
String::Normal::Config::AreaCodes
Valid US area codes.
All Config classes can be overriden by specifying your own custom text files.
normalizer
Quickly transform values without writing a script:
$ normalizer --value='Jones & Sons Bakeries' $ normalizer --value='Los Angeles' --type='city' $ normalizer --file=addresses.txt --type=address
