In order to better solve the problem of distributed query optimization, a querying optimization algorithm on GEP (QO-GEP) is present. On the basis of QO-GEP, distributed GEP query optimization on grid service (DGEPQO-GS) is proposed which combines with grid service. Simulated experiments shows that with the increment of the number of query relation, query time which QO-GEP carries out querying decreases apparently, meanwhile, with the number of grid nodes, the average querying success rate of DGEPQO-GS increases significantly.
