Problems solved by technology

Traditional group mining research based on frequent patterns usually only conducts a group mining on the target, and the mining target is often not comprehensive enough, especially the deep-level and multi-level mining of suspicious targets is particularly important

Abstract

The invention provides a target group multi-level mining method and device based on a frequent mode, and the method comprises the steps: S1, determining a given target, and setting a to-be-mined levelnumber N and a mining threshold value M; s2, accessing a database, and obtaining an original data set containing a given target; s3, setting n = 1; s4, reading the original data set to generate a maximum frequent item set containing a given target, and obtaining an nth layer of target group; s5, according to the nth layer of target group and the (n-th) th layer of target group, obtaining the target group of the nth layer of target group; the (n + 1) th layer of target group is generated by the first layer of target group, and when n is equal to 1, the (n-1) th layer of target group is generated; wherein the first-layer target group is a given target; s6, setting n = n + 1, and judging whether n is equal to N <-> or not; 1, if not equal to N- If yes, returning to execute the step S5, and if yes, executing the step S5; 1, ending the process; and S7, judging whether the number of all the maximum frequent item sets meets a mining threshold value M or not, and if not, ending the process.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a method and device for multi-level mining of target groups based on frequent patterns. Background technique [0002] Group mining is an important research direction in the field of data mining. Through group mining research on a given target, the target and its group can be found in a targeted manner. Traditional group mining research based on frequent patterns usually only conducts a group mining on the target, and the mining target is often not comprehensive enough, especially the deep-level and multi-level mining of suspicious targets is particularly important. Contents of the invention [0003] The present invention aims to provide a method and device for multi-level mining of target groups based on frequent patterns to overcome one of the above problems or at least partially solve any of the above problems. [0004] In order to achieve the above object, the technical...
