Abstract: A product matching system, comprising a memory configured to store a database of first product records, each record associated with values of one or more first attributes describing a respective product corresponding to the record. In addition, the system includes an input interface configured to receive a second product record associated with values of one or more second attributes describing a given product. A processing unit adapted to compare the values of the second attributes of second product records received through the input interface to the attributes associated with first product records in the database, to link the second attributes of second records determined to match a first record with the matching first database record, and to use the second attributes of the second records determined to match a first record, in comparing the first database record to further product records that are subsequently received through the input interface.
