Key personnel risk level assessment method and related equipment

Abstract

The invention provides a key personnel risk level assessment method and related equipment, and the method comprises the steps: obtaining a target personnel and related entities, entity attributes and relationships thereof through employing an entity-relationship joint extraction mode based on a pre-training model, constructing a target personnel knowledge graph, and obtaining a key personnel risk level assessment result; and filling the feature values of the risk influence factors of the target personnel of the given category according to a pre-constructed risk assessment index system. Based on a hybrid reasoning method in knowledge reasoning, knowledge reasoning and mining are carried out on hidden relation variables and features in the constructed knowledge graph, then entity and edge relations are complemented, and then data missing values of the risk assessment index system are further complemented based on the complemented knowledge graph. And finally, based on the complemented risk index data, outputting a risk score of the target person through a risk research and judgment model, thereby determining a risk level of the target person. The working efficiency in the target personnel management process can be effectively improved, and meanwhile the manpower management cost is reduced.

Description

technical field [0001] This application relates to the field of machine learning technology, in particular to a method for assessing the risk level of key personnel and related equipment. Background technique [0002] Under the influence of the continuous deepening of reform and opening up in recent years, the level of China's opening up to the outside world has been continuously improved, people's living standards have been greatly improved, population mobility has become more frequent, the opportunities and frequency of personnel mobility have greatly increased, and the complexity and difficulty of public security management have become increasingly prominent , Public security and law and order are facing new challenges. Effective assessment and timely warning of the possible harm to the society caused by the intervention target personnel can greatly enhance the effect of social security. [0003] Early warning and strike intervention are two aspects that cannot be neglec...

AI Technical Summary

Problems solved by technology

[0003] Early warning and strike intervention are two aspects that cannot be neglected to effectively control the potential risks of target personnel. However, in practice, the problem of "heavy strikes but little early warning" is common. The security risk assessment lacks sufficient scientific method support, and most of the actual security work Passive investigation work after the occurrence of crimes, and early warning work for early judgment of potential risks in a complete sense is still relatively small
