Abstract

A method for comparing two delimited strings, each of which has a plurality of substrings, includes pairing each substring in one of the delimited string with a corresponding substring in the other one of the delimited strings. The method further includes computing a proximity value for each pair of substrings, and computing a set of decaying weights corresponding to the pairs of substrings, multiplying the proximity value for each pair of substrings by the corresponding weight, and summing the weighted proximity values to obtain a strength of match between the delimited strings.
