In constructing bases or warehouses of knowledge, ontology of the arbitrary thematic branch, the issue of choosing the method of setting correspondence between terms (concepts) is always topical. Among the many approaches to setting the correspondence between the terms in bases or warehouses of the knowledge domain "Intelligence diagnostics of computer means" the most common is the use of tables with diagnostic information such as "object - property", which can be described by Cartesian product. But using a binary relation, we can answer the question: "Is there the relation?"Today it would be expedient to get the answer to the question: "Which of diagnostic means are more effective?"
