A computer-implemented method for finding an asymmetric relation between a plurality of target words is disclosed. The method includes preparing a plurality of image sets, each of which includes one or more images relevant to a corresponding one of the plurality of the target words. The method also includes obtaining a plurality of object labels for each of the plurality of image sets. The method further includes computing a representation for each of the plurality of the target words using the plurality of the object labels obtained for each of the plurality of image sets. The method includes further determining whether there is an asymmetric relation between the plurality of the target words using representations computed for the plurality of the target words.
