Prisoner risk assessment method based on multi-dimensional risk index

Abstract

The invention discloses a prisoner risk assessment method based on a multi-dimensional risk index. and relates to the technical field of big data in the computer information processing technology. Therisk assessment method comprises the following steps of S1, risk feature extraction based on prison information system data, S2, absolute risk index assessment, S3, relative risk index assessment, S4, abrupt change risk index assessment and S5, comprehensive risk index assessment. According to the prisoner risk assessment method based on the multi-dimensional risk index, prisoner multi-dimensional monitoring data provided by an existing information system can be fully utilized, and behavior characteristics and risks of a behavior mode are quantitatively expressed; according to the method, three evaluation dimensions of absolute risks of the prisoners in an evaluation system, relative risks compared with other prisoners and abrupt change risks of historical performance of the prisoners arecomprehensively considered, the possibility of early warning misjudgment is reduced to the maximum extent, and the method has higher self-adaptive capacity and meets actual requirements.

Description

technical field [0001] The invention relates to the field of big data technology in computer information processing technology, in particular to a risk assessment method for inmates based on a multidimensional risk index. Background technique [0002] With the gradual advancement of prison informatization and intelligent construction, the prison has built a series of business management systems including prison administration, punishment execution, life sanitation, labor reform, education reform, family calls, remote meetings, psychological assessment, etc.; at the same time A comprehensive security management platform including access control management, video surveillance, virtual inspection, sound and light alarm, digital grid, entry and exit management of foreign vehicles and personnel, emergency command and dispatch, system operation and maintenance, etc. has been built. These provide a large amount of basic characteristic data for the data analysis and judgment system ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a risk assessment method for inmates based on a multidimensional risk index, which solves the problem of qualitatively proposing a classification method for key criminals and recalcitrant criminals in prison inmate management standards. In actual operation, the data resources generated by relevant systems have not been fully utilized to carry out effective risk analysis and assessment of inmates, and the existing methods still have certain one-sidedness and inadequacies in the analysis and early warning.
