[0161] The embodiment of the present application provides a knowledge representation method in the field of financial business accounting rules. The field of business accounting rules mainly defines accounting rules or accounting calibers for the company's main operating indicators. The hardware platform used in the implementation of this application can be a general-purpose PC computer, and the software can be implemented using Python3.5. The steps of building the target domain knowledge base can include:
[0162] Determine three types of knowledge representation: concept words, events, and predicate logic formulas. Concept words include concept instances or concepts, which are the abstraction of objects in the target domain knowledge and express static knowledge. Events describe the behavior, action or state of objects, expressing dynamic knowledge. The predicate logic formula is an abstract description of the rules in the target domain knowledge (for example, the norms and...
example 1
[0179] Specifically, the service cost rules include: the expenditure incurred by activities or personnel directly related to the delivery of the service contract shall be included in the service cost, including the expenditure incurred directly in the service and the direct management and support of these personnel engaged in the service.
[0180] In the service cost rules, identifiable events include: generation of expenditure events, contract delivery events, service cost confirmation events, and identifiable concept instances include: activities and personnel. Therefore, the service cost rule can be expressed as: ЭxЭy (incurring expenditure (X, Y) Λ contract delivery (X) Λ (activity expenditure (Y) ∨ personnel expenditure (Y))) -> service cost (Y)
[0181] According to the generation rule of the predicate logic, it is determined that the rule header included in the service cost rule is a service cost confirmation event. The rule body includes: generating expenditure events,...

[0191] Labor cost rules, including mainly referring to the company's own and outsourced labor expenditures engaged in delivery activities, which can include wages, bonuses, social insurance, water and electricity fees, communication fees, travel expenses, etc.
[0192] In the labor cost rules, identifiable events include: expenditure events, contract delivery events, labor cost confirmation events, identifiable concepts include: company-owned manpower, outsourced manpower, expenditure content: wages, bonuses, social insurance, Water and electricity costs, communication costs, travel expenses, etc. Therefore, the predicate logic formula corresponding to the labor cost rule can be expressed as: ЭxЭy (expenditure (X, Y) Λ contract delivery (X) Λ (company personnel expenditure (Y) ∨ outsourcing personnel expenditure (Y))) -> labor cost (Y)
[0193] In the labor cost rule, the rule header is the service cost confirmation event. The rule body includes: generating expenditure event...
