NAME ^

Lingua-Orthon - Various measures of orthographic relatedness between two letter strings

VERSION ^

Version 0.02

SYNOPSIS ^

 use Lingua::Orthon 0.02;
 my $ortho = Lingua::Orthon->new();
 my $n = $ortho->index_identical('BANG', 'BARN');

DESCRIPTION ^

Lingua-Orthon - Various measures of orthographic relatedness between two letter strings

METHODS ^

new

 my $ortho = Lingua::Orthon->new();

Constructs/returns class object for accessing and passing params to other methods.

are_orthons

Returns 0 or 1 if the two strings qualify as 1-mismatch (Coltheart-type) orthons: same size, and only one discrepancy by substitution (no additions, deletions or transpositions).

index_identical

 $val = $orthon->index_identical($w1, $w2);

Returns the number of letters that are both identical and in the same serial position. So for BANG and BARN, 2 would be returned, for B and A, ignoring the common N as it is the third letter in BANG, the fourth letter in BARN, and so not in the same serial position across these two words.

hdist

 $val = $orthon->hdist('String1', 'String2');

Return the Hamming Distance between two letter strings.

ldist

 $val = $orthon->ldist('String1', 'String2');

Return the Levenshtein Distance between two letter strings.

len_maxseq

 $val = $orthon->len_maxseq('String1', 'String2');

Return the length of the longest common subsequence between two letter strings. This subsequence is found by the lcss method in String::LCSS_XS.

unique_abbrevs

 $val = $orthon->unique_abbrevs('String1', 'String2');

Return the number of unique abbreviations that can be made between two letter strings. This subsequence is found by the abbrev method in Text::Abbrev.

myers_ukkonen

 $val = $orthon->myers_ukkonen('String1', 'String2');

Return the Myers-Ukkonen distance between two letter strings, as found by the similarity method in String::Similarity.
