      Work Description: aherbert commented on issue #103: TEXT-126: Adding Sorensen-Dice similarity
algoritham
URL: https://github.com/apache/commons-text/pull/103#issuecomment-470532750
 
 
   I've had more of a think and have mocked an implementation for a generic `IntersectionSimilarity`.
   
   See [TEXT-155](https://issues.apache.org/jira/projects/TEXT/issues/TEXT-155) and the code
in the linked PR.
   
   This class can be used to compute the Sorensen-Dice similarity for bigrams or any other
type of structure that you would like to analyse from the `CharSequence`, e.g. characters,
bigrams, trigrams, n-grams, words, etc.
   
   Note: Sorensen-Dice similarity is the same as the F1-score

> I'd like to propose an extension to the algorithms for string similarity in *commons-text/src/main/java/org/apache/commons/text/similarity/*
>  Dice's Coefficient Algorithm can be helpful for many who are looking for ranking similarities
in strings.
