Jaro

Jaro refers to the Jaro distance, which is a metric used for measuring the similarity between two strings. It is particularly helpful in identifying typos and variations in data entry. The Jaro distance is calculated based on the number of matching characters between the two strings and the number of transpositions (where characters from one string appear in a different order in the other). The output value ranges from 0 to 1, where 0 indicates no similarity (no matching characters) and 1 indicates a perfect match. This metric is often used in record linkage and data matching applications, such as deduplication and in natural language processing tasks. The Jaro-Winkler distance is a variant of the Jaro distance that gives more weight to prefixes, making it more suitable for cases where common prefixes are meaningful.
