 abstract={In the paper, the multi-attribute objects with repeating qualitative values of attributes are considered. Each object is represented by a collection of multisets drawn from sets of values of the attributes.The effective procedure for comparing such objects as well as groups of such objects is developed. The proposed concept of the perturbation of one object by another is considered as the difference of the multisets representing the objects. The measure of perturbation describes remoteness between the considered objects, and, in general, is asymmetrical. A practical illustration of the proposed approach is carried out for the task of classification of text documents.},
