An improved method of matching a query string against a plurality of candidate strings replaces a highly computationally intensive string edit distance calculation with a less computationally intensive lower bound estimate. The lower bound estimate of the string edit distance between the two strings is calculated by equalising the lengths of the two strings by adding padding elements to the shorter one. The elements of the strings are then sorted and the substitution costs between corresponding elements are summed. <IMAGE> |
