taxamatch_rb is a ruby implementation of Taxamatch algorithms developed by Tony Rees:

The purpose of Taxamatch gem is to facilitate fuzzy comparison of two scientific name renderings to find out if they actually point to the same scientific name.

require 'taxamatch_rb'
tm =
tm.taxamatch('Homo sapien', 'Homo sapiens') #returns true
tm.taxamatch('Homo sapiens Linnaeus', 'Hommo sapens (Linn. 1758)') #returns true
tm.taxamatch('Homo sapiens Mozzherin', 'Homo sapiens Linnaeus') #returns false

taxamatch_rb is compatible with ruby versions 1.9.1 and higher


$ sudo gem install taxamatch_rb


require "taxamatch_rb"

# To find version

# To start new instance of taxamatch
tm =
  • compare full scientific names
tm.taxamatch("Hommo sapiens L.", "Homo sapiens Linnaeus")
  • preparse names for the matching (necessary for large databases of scientific names)
p =
parsed_name1 = p.parse("Monacanthus fronticinctus G√ľnther 1867 sec. Eschmeyer 2004")
parsed_name2 = p.parse("Monacanthus fronticinctus (Gunther, 1867)")
  • compare preparsed names
tm.taxamatch_preparsed(parsed_name1, parsed_name2)
  • compare genera
tm.match_genera("Monacanthus", "MONOCANTUS")
  • compare species
tm.match_species("fronticinctus", "frontecinctus")
  • compare authors and years
Taxamatch::Authmatch.authmatch(["Linnaeus"], ["L","Muller"], [1786], [1787])
