For the application background on a guidance of audit information resource, this paper constructs the ontology of audit methods which is suitable for medical insurance in audit field, and provides information basis for the ontology-based rule reasoning, through utilizing the collected relevant information of audit methods in actual work of medical insurance. Then, the paper mainly researches the rule reasoning algorithm—forward rule rapid matching Rete algorithm in expert system. Aiming at the existing problems in Rete algorithm, the paper introduces the improved method of active hash. Finally, the paper verifies that the improved Rete algorithm can improve implementation efficiency, and has practical significance in the intelligent retrieval system.
