Traditionally, approximate string matching algorithms are classified into two categories: on-line and off-line. With on-line algorithms the pattern can be processed before searching but the text cannot. In other words, on-line techniques do searching without an index. Early algorithms for on-line approximate … See more In computer science, approximate string matching (often colloquially referred to as fuzzy string searching) is the technique of finding strings that match a pattern approximately (rather than exactly). The problem of … See more The closeness of a match is measured in terms of the number of primitive operations necessary to convert the string into an exact match. This number is called the See more Common applications of approximate matching include spell checking.
