The full question is:
If epistemology cannot and gnoseology can only partially deal with it, what is the name and essence of the theory of the knowledge self-acquired and self-aggregated by specific engineered systems with cognitive (learning, reasoning, deciding) capabilities?
Epistemology is deemed to deal with construction and justification of (context-independent) scientific knowledge. Gnoseology is most often seen as the theory of partial approximate knowledge by an individual, but some gnoseology writers also talk about dealing with heuristic, intuitive, common-sense, instinctual, sensual, experienced, etc. knowledge in general while they discuss concerns for gnoseology.
