Package details
String::Approx lets you match and substitute strings approximately. With this
you can emulate errors: typing errorrs, speling errors, closely related
vocabularies (colour color), genetic mutations (GAG ACT), abbreviations
(McScot, MacScot).
NOTE: String::Approx suits the task of string matching, not string comparison,
and it works for strings, not for text.
If you want to compare strings for similarity, you probably just want the
Levenshtein edit distance (explained below), the Text::Levenshtein and
Text::LevenshteinXS modules in CPAN. See also Text::WagnerFischer and
Text::PhraseDistance. (There are functions for this in String::Approx, e.g.
adist(), but their results sometimes differ from the bare Levenshtein et al.)
