each database representative is represented by k different keys generated by the k hash function groups. For example two similar database representatives [E.sub.1], [E.sub.2] having the two keys' sets [key.sub.1] = {[g.sub.1]([E.sub.1]), ..., [g.sub.k]([E.sub.1])}, and [key.sub.2] = {[g.sub.1]([E.sub.2]), ..., [g.sub.k]([E.sub.2])} respectively, should share more elements among their corresponding sets, Charikar [3].
