The Fuzzy Matching technique in computer science helps identify two elements of text strings that are similar but not precisely the same. In other words, it determines the degree of closeness of two different strings.
Fuzzy matching works by combining certain general notions from fuzzy logic and mathematics with a special recursive piecewise function meant to calculate something called the Levenshtein distance between two given strings.
Fuzzy matching can certainly be a very powerful tool. When used properly, it can organize databases, correct spelling mistakes, refine search results, sequence genetic information, and even detect financial fraud.
