Each object is represented by a collection of multisets drawn from sets of values of the attributes. The new measure of perturbation of one group of objects by another group of objects was introduced. A practical illustration of the proposed approach is carried out for the task of grouping of text documents described by multisets.}, title={Bidirectional Comparison of Multi-Attribute Qualitative Objects}, type={Text}, URL={http://www.rcin.org.pl/Content/109219/PDF/RB-2016-39.pdf}, keywords={Multi-attribute qualitative objects, Asymmetry of objects’ proximity, Obiekty jakościowe z wieloma atrybutami, Asymetria bliskości obiektów, Perturbation of multisets, Perturbacja wielozbiorowa}, }
