18. The computer-readable media of claim 17 , wherein the determining similarity among the corresponding field values of the database records comprises: assigning an n-degree hyperspace attribute to each database record, where n represents a number of data fields of interest, and wherein the hyperspace attribute corresponding to two database records is correlated with a similarity of the corresponding field values of the two database records; determining membership of each database record in a plurality of hyperspace clusters based at least in part on the hyperspace attributes; assigning, to each record, a cluster ID and a match value reflecting a likelihood that the record is a member of a particular hyperspace cluster; and linking related records based at least in part on the cluster ID and match value.
