Levenshtein Ratio Rule Tester
Enter a list of value pairs to test against the lev-ratio rule. The Levenshtein
Ratio measures how similar two strings are based on the number of single-character edits
required to transform one into the other. The score ranges from 0 (completely
different) to 100 (identical). A pair is considered a match when its score
meets or exceeds the threshold you specify below. Results include both raw and normalized
comparisons so you can see how normalization affects fuzzy matching.
Score formula: round(100 × (len(A) + len(B) − distance) / (len(A) + len(B)))
