A method of identifying related objects in a computer database, comprising: (a) obtaining a feature vector that describes an existing object; (b) generating comparison scores between the feature vector and plural sample vectors; (c) identifying a set that includes at least one designated vector, from among the sample vectors, by evaluating the comparison scores generated in step (b); (d) searching a computer database for matches between at least one label for the at least one designated vector and labels for representative vectors for a plurality of other objects represented in the computer database; and (e) identifying at least one related object based on at least one match identified in step (d).
