Schemes for data mining and combination in some higher abstract structure level. First, the classical dataset, classified by the four types of scales of measurement (Stevens classification), is re-interpreted as a group/field-like operational structure. Second, a vector ‘Rj’ is defined that is composed as the product of each type of operation for all datasets other than for those classified as “Nominal scale”. Third, the ‘Rj’s are constituted as an “operational tree”. Fourth, ‘Rj’ with any arbitrary j (j = 1, 2,…, m) could be mined and combined as “hierarchical clusters”.
