The application provides a method and
system for checking the cross-
modal information consistency of a
maintenance plan based on a
large model, and relates to the technical field of
big data analysis. The method comprises the following steps: identifying a target
maintenance plan through a power
large model, determining key maintenance content, an unstructured proportion, and an attachment type complexity; obtaining a text
data complexity and a business
risk index based on key maintenance content analysis, as a first checking difficulty coefficient and a second checking difficulty coefficient; determining a third checking difficulty coefficient according to the unstructured proportion and the attachment type complexity evaluation; taking the expected review
time limit of the target
maintenance plan as a constraint, formulating an adaptive checking depth and an adaptive checking breadth based on the first checking difficulty coefficient, the second checking difficulty coefficient, and the third checking difficulty coefficient; and performing cross-
modal information consistency checking on the target maintenance plan according to the adaptive checking depth and the adaptive checking breadth. The dynamic allocation of resources for checking the cross-
modal information consistency of a maintenance plan is achieved.
