The "Levenshtein distance" is a measure of the similarity between two strings,
this algorithm is also refered to as "edit distance". The "Levenshtein distance"
was named after the russian scientist "Vladimir Levenshtein", who has discovered
it back in 1965. The smaller the distance between two strings, the closer are
those strings syntacticaly. The "Levenshtein distance" distance is computed by
calculating the minimum number of operations that has to be made to transform
one string to another one,usualy this operations are: replace,insert or delete a character
example: we can change the word: "mathematics" to "mathematician" by changing one character
and by inserting two more characters at the end.(we can replace "s" by "i" and
also insert "a" and "n" after that). The total number of operations that was needed in this
case to change "mathematics" to "mathematician" was 3 operations and since it is
also the smallest number of operation that can be use transform one of these strings
to the other one, that value is also a measure of the "Levenshtein distance" between
these two strings. There has been many application of the "Levenshtein distance", here is a few of them:
Spell Checking, Speech Recognition, Pattern Recognition etc.
