Simetric

Simetric provides facilities to perform approximate string matching and measurement of string similarity/distance. The library is focusing on speed and completeness.

Metrics

• Jaro
• Jaro–Winkler

Installation

Add Simetric as a dependency to your mix.exs file:

defp deps do
  [{:simetric, "~> 0.0.1"}]
end

After you are done, run mix deps.get in your shell to fetch the dependencies.

Usage

Metrics calculate the similarity of two strings as a float value between 0 (equates to no similarity) and 1 (is an exact match).

Jaro distance:

Simetric.Jaro.compare("dwayne", "duane") # 0.8222222222222223
Simetric.Jaro.compare("hardin", "martinez") # 0.7222222222222222
Simetric.Jaro.compare("even", "odd") # 0.0

Jaro–Winkler distance:

Simetric.Jaro.Winkler.compare("dwayne", "duane") # 0.8400000000000001
Simetric.Jaro.Winkler.compare("hardin", "martinez") # 0.7222222222222222
Simetric.Jaro.Winkler.compare("same", "same") # 1.0
