Embodiment 1

[0056] see figure 1 It is a schematic flow chart of a method for constructing a numerical fusion model provided in Embodiment 1 of the present invention. The method includes the following steps:

[0057] S11. Obtain information of each dimension of numerical fusion;

[0058] It can be understood that the numerical fusion dimension information includes dimension quantity and dimension data, wherein the dimension data is a numerical statistical sample value. Multidimensional statistical analysis can only be carried out when the number of dimensions and dimension data are determined. For example, when applied to the public security data theft scenario, when analyzing whether a police officer has the possibility of data theft, the dimension data includes the number of visits to the public security website, the cumulative time of website visits, and the Public Key Infrastructure (PKI) of the public security. ), the corresponding number of dimensions is 3.

[0059] S12. According...

Embodiment 2

[0067] Referring to embodiment one of the present invention and figure 1 The specific process of steps S11 to S14 described in the present invention, the application scenario of the embodiment of the present invention is aimed at the data theft scenario of the public security, of course, it can also be other scenarios that require numerical fusion analysis and processing, and the present invention does not limit it. Only the public security data theft scenario is used to illustrate the solution, other scenarios can refer to the processing method of this scenario, and the corresponding method changes according to different scenarios also fall within the scope of protection of the present invention.

[0068] First of all, it is necessary to obtain the dimensional information of numerical fusion. For the public security data theft scenario, due to the limitations of various factors such as on-site data collection, data volume, and leaking conditions, the dimensional information in...

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a numerical fusion model construction method and device. Background technique [0002] In the actual life or production process, it is often necessary to make an objective and comprehensive evaluation of a person or thing. For example, in the public security system, it is necessary to analyze whether a police officer has the possibility of data theft. Usually, when performing this kind of evaluation, there are multiple corresponding refined small indicators. After these small indicators are determined, the comprehensive evaluation indicators are calculated according to the corresponding fusion algorithm, and finally the corresponding comprehensive evaluation indicators are comprehensively, finely and objectively evaluated. person or thing. [0003] At present, the processing flow of the commonly used numerical fusion algorithm is: after determining the current eval...
