From the applied point of view, it is very important to explain correctly the meaning of clustering results. The approach explain the meaning of clustering results with the help calculating the ratio of frequency is given. The effectiveness the method is illustrated by the numeric experiments. Lastly, some problems that will be studied further are pointed out.
