Abstract: Aiming to meet the precision demand when query the equipment integrated logistic support data in the integration data environment by IETM, a optimizing sort of IETM retrieve results based on historical feedback was built. It analyses the behaviors about browsing and clicking while querying the data, quantifies the influence factor that influencing the result of retrieve from the personal behavior feedback and the historical behavior feedback, and realizes finally the optimizing sort of IETM retrieve results in the integration data environment. The experimental result shows that this arithmetic of optimizing sort can promote the precision demand in base of keeping the recalling demand of equipment support data.
