Gang mining method, device and equipment and storage medium

Abstract

The invention relates to a gang mining method, device, equipment and a storage medium. The method comprises the steps of obtaining trajectory data of all objects in a troubleshooting area; performingserialization processing on the trajectory data of all the objects to obtain a trajectory sequence of each object; lCSS-based algorithm, combining the size relationship between the time difference corresponding to the final track points of every two objects and a preset time difference threshold value; calculating the longest common subsequence length between the trajectory sequences of every twoobjects according to the difference between the time corresponding to the starting trajectory point of one object and the time corresponding to the final trajectory point of the other object in everytwo objects and the time difference threshold; and performing clustering analysis according to the longest common subsequence length between the trajectory sequences of every two objects to obtain a trajectory clustering result of the troubleshooting area as a gang mining result. By adopting the method and the system, gang mining can be accurately realized.

Description

technical field [0001] The present invention relates to the technical field of data mining, in particular to a group mining method, device, equipment and storage medium. Background technique [0002] At present, the incidence rate of gang crimes continues to rise, causing serious social harm. Compared with the criminal behavior of a single criminal, due to the complex organizational structure of criminal gangs, their criminal behavior is more complicated, and it is difficult for law enforcement agencies to investigate and crack down on it. Therefore, it is of great significance to quickly and accurately identify members of criminal gangs and dig out criminal gangs to improve the effectiveness of combating criminal gangs. [0003] With the construction of informatization, law enforcement agencies have obtained more and more social data, which provides important support for the mining of criminal gangs. However, due to the structural nature of criminal gangs, it is difficult...

AI Technical Summary

Problems solved by technology

However, due to the structural nature of criminal gangs, it is difficult and inefficient to mine criminal gangs by analyzing a large amount of social data only manually. Therefore, efficient and accurate big data analysis methods are urgently needed for gang mining.
