Method for estimating updated multiple ranking using pairwise comparison data to additional queries

摘要

According to one embodiment of the present invention, a multiple ranking estimating method using pairwise comparison data comprises the steps of: inputting information on pairwise comparison data as a first input data; calculating multiple ranking data based on the input data; selecting additional queries based on the calculated multiple ranking data; receiving a second input data on pairwise comparison data for the additional queries; and updating the multiple ranking data based on the first and second input data. At least one among the first and second input data comprises a set of a plurality of responders, a set of a plurality of items, and a set of a plurality of pairwise comparison data for a plurality of items. Each of pairwise comparison data of the plurality of pairwise comparison data is data determining preferences between two items based on one determination standard among a plurality of determination standards. According to one embodiment of the present invention, if there are a plurality of determination standards for given pairwise comparison data, the method can estimate a ranking of an item according to a plurality of determination standards, and furthermore, analyze each characteristic of the plurality of determination standards, and provide the same.
