It is named after Vladimir Levenshtein, who considered this distance in 1965. [11 b Print export For example, the Levenshtein distance between " kitten'andsittingis 3, since the following three edits change one into the other, and there is no way to do it with fewer than v languages three edits. the objective is to find matches for short strings, for instance, strings from a dictionary, in many longer texts, in situations where a sn Here. one of the strings is typically short, while the other is arbitrarily long. This has a wide range of applications, for insta ce, spell checke correcton syst optical character rece and software to assist natural language translation The Levenshtein distance can also be computed between two longer strings, but the cost to compute it, which is roughly proportional to the product of the two string lengths, Levenshtein distance is not the only popular notion of ed distance. Variations can be obtained by changing the set of allowable edit operations: for instance, is available, and each operation is assigned a cost(possibly infinite) further generalized by ence alignment algorithms such h make an operation s cost depend on where it is appled. Computing the Levenshtein distance is based on the observation that if we reserve a matri to hold the Levenshtein distances between all prefixes of the first string and all prefixes of the second, then we can compute the values in the matrix by flood fling the matrix, and thus find the distance between the two full strings as the last value http://en.wikipedia.org/wiki/levenshtein_disTance 1/28/2021 Taste@ ICDE2012 4 Wikipedia http://en.wikipedia.org/wiki/Levenshtein_distance Automatically add the links 1/28/2021 Taste @ ICDE2012 4/42
