I have a good understanding of various edit-distance algorithms in JavaScript, but my goal is to calculate text similarity as a percentage based on them. Can anyone provide guidance on how to implement this feature?
I have a good understanding of various edit-distance algorithms in JavaScript, but my goal is to calculate text similarity as a percentage based on them. Can anyone provide guidance on how to implement this feature?
Calculate the maximum distance between a string of length n and a string of length m. If the maximum distance is equal to n + m, then the percentage will be:
100 - 100 * edit_distance(a, b) / (a.length + b.length)
Using Levenshtein distance with a cost of 1 for each insert, replacement, deletion results in the maximum possible distance being max(n, m). In this case, the percentage will be:
100 - 100 * Levenshtein(a, b) / Math.max(a.length, b.length)
