public interface ObjectSimilarityScore<T,R> extends BiFunction<T,T,R>
Scores the similarity between two Objects of the same type.

A string similarity score is intended to have some of the properties of a metric, yet allowing for exceptions, like the Jaro-Winkler similarity score.

A similarity score is the function d: [X * X] -&gt; [0, INFINITY) with the following properties:

  • d(x,y) &gt;= 0, non-negativity or separation axiom
  • d(x,y) == d(y,x), symmetry.

Notice, these are two of the properties that contribute to d being a metric.
