Abstract: For clustering of the nonnumeric objects the similarity matrix of the expert judgments is used. The clustering is performed by diagonalization of similarity matrix. The variational and the heuristic diagonalization algorithms are proposed.

Keywords: nonnumeric objects, similarity matrix, cluster-analysis.
