This article is devoted to a solution of the problem of collecting and classification of the expert knowledge acquired during the operation of information systems aimed to organize expert knowledge bases. As perspective approach ontological theory use is offered; it provides a basis for building mathematical model of knowledge representation. Organization of objects hierarchy is carried out with use of classification based on structural approach and the OSI/ISO reference model. The article also outlines the basic principles of software implementation of offered methods and results of its testing.
