This package can calculate the similarity level of two text strings.
It can take two text strings and apply algorithms to calculate a number that represents the similarity between those strings.
The class that implements the Hamming distance algorithm returns the number of text characters that are different in each string.
The class that implements the Levenshtein algorithm returns a number that represents the number of steps that are necessary to change the first string into the second strings. | |
