Jaccard Similarity Coefficient

Compare the overlap between two sets — the intersection divided by the union of character bigrams.

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

How it works

The Jaccard similarity coefficient measures the overlap between two sets by dividing the size of their intersection by the size of their union. When applied to strings (using character bigrams as set elements), it measures how many character pairs the strings share. A score of 1 means identical sets, 0 means no overlap. Jaccard similarity is particularly useful for comparing addresses and multi-word strings where word order may vary.
