ABSTRACT

The existing methods of classifier assessment use a set of classes which are comparable both by the probability of appearànce and by semantical interrelation that is they are semantically independent. The developed theory of calculus over classification permits solving the issue of classifier assessment for hierarchical classifications. This papper contains the example of calculation of the precision and completeness of classes of plane-level and multi-level classification with the same confusing matrix.

KEYWORDS

classification, classifier, semantic, precision, completeness, measure of difference.
