3. The method of claim 1 , wherein determining the similarity among the corresponding field values of the database records comprises: assigning a hyperspace attribute to each database record, 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 the match value.

The method of claim 3 , further comprising merging database records having hyperspace attribute differences within a predefined criteria to eliminate similar exemplars that are likely to represent a same entity, the merging resulting in a reduced set of database records.
