The invention discloses a power communication maintenance
ticket approval method and
system. The method comprises the steps of obtaining to-be-approved
electric power communication maintenance
ticket data; performing semantic understanding and
information extraction on to-be-approved
electric power communication maintenance
ticket data by using a neural
network module, and outputting structured
semantic information; inputting the structured
semantic information into a symbol reasoning module, performing
logical reasoning and compliance
verification by the symbol reasoning module based on a differentiable symbol rule base, and outputting an approval result; the method comprises the following steps: converting an
electric power communication maintenance ticket approval rule into a symbolic logic expression with a weight by adopting a differentiable logic operator, and constructing a differentiable symbolic rule base; and constructing a double-layer optimization framework, and jointly optimizing parameters of the neural
network module and weights of rules in the differentiable symbol rule base based on upper-layer approval task loss and lower-layer symbol rule logic consistency loss. According to the method, the examination and approval efficiency, accuracy and auditing performance are remarkably improved, and the method is suitable for intelligent
processing of
power grid communication maintenance business.
