NAME

Lingua::Word::Parser - Parse a word into known and unknown parts

VERSION

version 0.05

SYNOPSIS

use Lingua::Word::Parser;
my $p = Lingua::Word::Parser->new(
   word => 'abioticaly',
   file => 'eg/lexicon.dat',
);

# Or with a database source:
$p = Lingua::Word::Parser->new(
   word   => 'abioticaly',
   dbname => 'fragments',
   dbuser => 'akbar',
   dbpass => 's3kr1+',
);

my ($known) = $p->knowns;
my $combos  = $p->power;
my $parts   = $p->score_parts;
my $scored  = $p->score;

# The best guess is the last sorted score-set:
warn Dumper $scored->{ [ sort keys %$scored ]->[-1] };

DESCRIPTION

A Lingua::Word::Parser breaks a word into known affixes.

A (word-part => regular-expression) lexicon file must have lines of the form:

a(?=\w)        opposite
ab(?=\w)       away
(?<=\w)o(?=\w) combining
(?<=\w)tic     possessing

A database lexicon must have (affix, definition) records of the form:

       affix     definition
-----------------------------
       a(?=\w)   opposite
       ab(?=\w)  away
(?<=\w)o(?=\w)   combining
(?<=\w)tic       possessing

METHODS

new()

$x = Lingua::Word::Parser->new(%arguments);

Create a new Lingua::Word::Parser object.

Arguments and defaults:

word:   undef
lex:    undef
dbuser: undef
dbpass: undef
dbname: undef
dbtype: mysql
dbhost: localhost

knowns()

Fingerprint the known word parts.

power()

Find the "non-overlapping powerset."

score()

$score = $p->score( $open_sparator, $close_separator, $line_terminator );

Score the known vs unknown word part combinations into ratios of characters and chunks or parts or "spans of adjacent characters" as a collection of strings.

If not given, the $open_sparator and $close_separator are '<' and '>' by default.

score_parts()

$score = $p->score_parts( $open_sparator, $close_separator );

Score the known vs unknown word part combinations into ratios of characters and chunks or parts or "spans of adjacent characters."

If not given, the $open_sparator and $close_separator are '<' and '>' by default.
