摘要
An improved system and method for aggregating a list of top ranked objects from ranked combination lists using an early termination algorithm is provided. Ranked lists of individual object attributes may be aggregated into ranked lists of combination object attributes. The ranked lists of object attributes, including ranked lists of individual object attributes as well as ranked lists of combination object attributes, may be scanned in parallel. A fixed number of top scoring objects may be stored in a results list of top ranked objects. An upper bound of best possible aggregation scores of unseen object in the ranked lists of object attributes may be computed to incorporate the extra information given by the combination lists of attributes. If the upper bound computed is less than the score of top scoring objects in the results list, then the top scoring objects in the results list may be output.
