A method, system, and/or computer program product classifies a plurality of objects displayed on a display device and displays the classified plurality of objects. The method comprises: selecting one object from a plurality of objects as a selected object; and classifying the plurality of objects, where classification of each of the plurality of objects is based on a degree of association with the selected object. Classifying the plurality of objects comprises: reading a feature setting for computation of the degree of association; specifying a plurality of features that are subject to the computation of the degree of association; computing, for each of the plurality of objects, the degree of association based on a difference in feature value from the selected object with regard to the plurality of features; and dividing the plurality of objects into a plurality of groups, where each group is based on the degree of association.
