Abstract: A system (1) generates an output indicating scores for the extent of matching of pairs of data records. Thresholds may be set for the scores for decision-making or human review. A vector extraction module (12) measures similarity of pairs of fields in a pair of records to generate a vector. The vector is then processed to generate a score for the record pair.

Abstract: This invention refers to an automatic design process comprising the steps of:- (1)writing a target specification of an item to be designed to a partitioned section of a memory circuit; (2)automatically determining an address for a case stored in a case-base by reference to the target specification;(3)retrieving the case from the case-base and writing the retrieved case to a partitioned section of the memory circuit; and (4)adapting the retrieved case into conformity with the target specification, and writing the adapted case to a partitioned section of the memory circuit as a target solution. Preferably, the process further comprises successive cycles of retrieving a case and adapting the retrieved case, each cycle being initiated by writing of a target specification representing a component of the item to the target specification section of the memory circuit.
