It is suggested, when creating knowledge management mechanisms to avoid any extremes in their presentation: various "centrisms", hypertrophy in the use of both mathematical and verbal-meaningful knowledge. It is shown that it is important to observe the principle of "ethics of engagement ", which can be implemented on the basis of a productive interdisciplinary synthesis. The stages of knowledge presentation are considered on the basis of the typology of interdisciplinarity. It is argued that the stage of semantisation (conceptualization) of knowledge representation, when creating control systems, should be preceded by the stage of ontologization. It enhances the distinctiveness of knowledge representation. The stage of ontologization is necessary for the construction of more detailed explanatory constructions, due to the greater formalization of the ontological representation, in comparison with the stage of semantisation. It is assumed that the taxonomy stage can become the basis for the ontologization of knowledge representation, for example, in knowledge engineering.
