Risk assessment method, device, computer device and storage medium

Abstract

The invention relates to a risk assessment method, comprising the following steps: receiving the risk evaluation request sent from a terminal; searching a social network graph; monitoring risk factors; based on the risk factors, determining the first-level activated nodes in the social network graph; according to the social network graph, calculating the accumulated weights of the first-level activated nodes to their neighboring connected nodes and determining whether the accumulated weights exceed the preset activation threshold for the neighboring connected nodes so as to determine the second-level activated nodes; according to the first-level activated nodes and the second-level activated nodes, determining the next-level activated nodes until the accumulated weights of the connected nodes are transmitted to an evaluation body to obtain the accumulated weights of the evaluation body, to further obtain the risk evaluation result of the evaluation body and to transmit the risk evaluation result to the terminal. The above method achieves higher evaluation efficiency and can analyze the risk transmission process dynamically.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a risk assessment method, device, computer equipment and storage medium. Background technique [0002] Risk assessment refers to the quantitative evaluation of the possible impact and risk brought by the event on the enterprise or individual that you want to evaluate before or after the risk event occurs (but not yet ended). That is, risk assessment is to quantitatively evaluate the possible degree of impact or loss caused by an event or thing. [0003] The assessment methods commonly used in traditional risk assessment mainly include: expert forecasting method, which refers to a group of experts composed of multiple experts conducting forecasting discussions through symposiums. This method not only has low assessment efficiency, but also cannot ensure that it can objectively reflect reality; LEC The risk assessment method is a quantitative calculation method of risk. ...

AI Technical Summary

Problems solved by technology

The division of hazard levels by the LEC risk assessment method is to a certain extent based on empirical judgments, and its application has limitations and cannot be universally applied.

That is to say, the traditional risk assessment methods are mostly empirical static decision-making assessment methods, the assessment efficiency is low, and the assessment process is not retrospective
