AI Technical Summary
Existing technologies have low accuracy when facing complex invoice review scenarios, cannot effectively cope with diverse invoice sources and complex business scenarios, lack system flexibility, lack compliance verification and traceable logs, and have limited automation.
A bill verification method based on a large language model is adopted. By constructing a semantically related bill type library, field library, and rule library, and combining the semantic understanding capability of the large language model, the type is determined based on the visual features of the bill image layout. Customized prompt words are constructed for semantic parsing and automated verification is performed.
It significantly improves the accuracy and robustness of invoice review in complex scenarios, realizes an intelligent invoice review process, gets rid of the dependence on fixed templates, and ensures the business compliance and traceability of review results.
