Abstract
A method for transaction analysis comprises extracting a plurality of character groups from a plurality of transaction identifiers, determining an inverse document frequency value for each of the plurality of character groups, generating, for a first transaction and a second transaction, respectively, a first transaction signature and a second transaction signature corresponding to the plurality of character groups, and computing a distance between the first and second transaction signatures.
