Abstract
A system associates sequentially descending weights with items in a reference list. The system identifies overlapping items from the first position to the second position in both the reference list and a test list. The system determines a weighted overlap for the overlapping items by combining the weights for each overlapping item to create a reference item weight, combining the weights for each item from the first position to the second position in the reference list to create a reference position weight, and determining the ratio between the reference item weight and the reference position weight. The system identifies overlapping items from the first position to the third position in both the reference list and the test list, and then determines a weighted overlap for these overlapping items. The system outputs the average weighted overlap as an efficiency evaluation of the information retrieval system that created the test list.
