Abstract
A high qualified pattern mining method is provided. The high qualified pattern mining method is performed by one or more processors, and includes determining a support degree of an item set to be processed in a transaction database; determining a weight occupancy of the item to be processed in the transaction database; and determining that the item set to be processed is a high qualified pattern based on the support degree not being less than a product of a preset lowest support degree threshold value and a total number of transactions in the transaction database, and the weight occupancy not being less than a preset minimum weight occupancy threshold value.
