A data processing method, device and apparatus for an output object and a non-volatile computer storage medium. The method comprises: acquiring a feature property of each of at least two output objects (101); then acquiring, according to the feature property of each output object, the intersection of each pair of the output objects (102); acquiring, according to the feature property of each output object and the intersection of each pair of the output objects, a similarity matrix (103); and thereby, performing, according to the similarity matrix, visualized output for each output object (104). A bidirectional relationship between each pair of output objects can be represented by a similarity matrix obtained according to a feature property of each output object and the intersection of each pair of the output objects, and therefore obtained similarities between all pairs of the output objects are the real similarities of the pairs of the output objects, thus improving the reliability of visualization of the output objects.
