System score coverage adjusting and optimizing method

The method comprises the following steps: crawling a standard text related to industrial standard online information safety through a crawler frame webmagic as original data, performing structured extraction on an industrial standard file needing to be updated through a preset text matching rule to obtain structured standard data, establishing a weight table of fields and risks, obtaining an updated industrial standard text, and updating the industrial standard file according to the structured standard data. By evaluating the difference between new and old standard texts and the difference between new and old scoring standard texts, mining a mapping relationship between the differences, and recognizing and updating industry standard contents through a difference evaluation system, dynamic updating of a sorting list needing to be audited and calibrated is realized, the scoring standard coverage of the system can be more comprehensive, and the evaluation efficiency of the system is improved. Negative effects caused by incomplete system evaluation are reduced; according to the method, national standards in related aspects can be matched in a targeted manner, so that the scoring standard which is artificially established can be combined with the latest national standards, and the scoring standard covers more national standards, so that the scoring standard is more normative and more feasible.
