Jaro Similarity

Calculate the Jaro similarity between two strings — a foundational metric in record linkage and deduplication.

Tilores uses Jaro similarity in production — so you can automate matching with rules you configure.

How it works

The Jaro similarity measures the similarity between two strings based on the number of matching characters and their order. It accounts for transpositions (characters that match but are in different positions). The result ranges from 0 to 1, where 1 means the strings are identical. Jaro similarity is the basis for the Jaro-Winkler metric and is widely used in census data processing and medical record linkage.
