Representational Limits in Cognitive Architectures

This paper proposes a focused analysis on some problematic aspects concerning the knowledge level in General Cognitive Architectures (CAs). In particular, it addresses the problems regarding both the limited size and the homogeneous typology of the encoded (and processed) conceptual knowledge. As a possible way out to face, jointly, these problems, this contribution discusses the possibility of integrating external, but architecturally compliant, cognitive systems into the knowledge representation and processing mechanisms of the CAs. Keywords—cognitive architectures, knowledge representation, knowledge level, common-sense reasoning.
