             Summary: Have a clear distinction between Edit Distance, String Similarity, Score, Metric, etc
                 Key: TEXT-21
                 URL: https://issues.apache.org/jira/browse/TEXT-21
             Project: Commons Text
          Issue Type: Improvement
            Reporter: Bruno P. Kinoshita
            Assignee: Bruno P. Kinoshita


From LANG-1269.

A user reported a nomenclature issue in [lang], which occurs in [text] as well.

Currently we have an interface called EditDistance, with the following implementations:

* CosineDistance
* HammingDistance
* JaroWrinklerDistance
* and LevenshteinDistance

JaroWrinkler is actually a similarity score, and not a distance. We have other classes in the oact.similarity package too.

* CosineSimilarity
* FuzzyScore

We need to provide users a clear distinction on what we call an edit distance, similarity or score.
