Abstract: Through analyzing the drawback of existing matching method,a new method was proposed to select matching relation between elements based on the dependency conflict.At first,the candidate match of elements in target schema is selected,and then the value of conflict is calculated for each overall matching solution,at last the solution with minimum value of conflict is selected as the final result.Experimental results show that the precision of matching result is increased and the time for the optimization procedure of the mapping data is reduced with this strategy.
