Provides classes for calculating distances and fuzzy match similarities between two strings. Also provides implicits for using distance and fuzzy match scores as an operator, like:
Includes functionality for phonetic comparisons between strings.
Overview
The main class to use is com.github.vickumar1981.stringdistance.StringDistance
If you include com.github.vickumar1981.stringdistance.StringConverter, you can convert/use the string distance and score functions as an operator between two strings.
To compare two strings phonetically, i.e. if they sound alike, use the com.github.vickumar1981.stringdistance.util.StringSound class.
To use in Java, please use the corresponding classes in the com.github.vickumar1981.stringdistance.util package.
