Would something like the Levenshtein edit distance assist you (the greater the value, the greater the two strings' distance)?

use strict; use warnings; use Text::LevenshteinXS qw(distance); my @var; $var[0] = "Gallia est omnis divisa in partes tres"; $var[1] = "Gallia est omnis divisa in ..."; $var[2] = "Gallia est omnis ..."; $var[3] = "Gallia"; $var[4] = "... omnis divisa in ..."; $var[5] = "Gallia est ... tres"; $var[6] = "Gallia ... partes tres"; $var[7] = "Gallia est ... partes tres"; $var[8] = "Gallia ... divisa ... tres"; $var[9] = "... tres"; $var[10] = "quattuor"; print qq{Each string's 'distance' from "$var[0]":\n\n}; for ( 0 .. $#var ) { print distance( $var[0], $var[$_] ) . " - $var[$_]\n"; }

Output:

Each string's 'distance' from "Gallia est omnis divisa in partes tres" +: 0 - Gallia est omnis divisa in partes tres 11 - Gallia est omnis divisa in ... 21 - Gallia est omnis ... 32 - Gallia 21 - ... omnis divisa in ... 22 - Gallia est ... tres 19 - Gallia ... partes tres 15 - Gallia est ... partes tres 18 - Gallia ... divisa ... tres 33 - ... tres 34 - quattuor
