%A Carlos Gershenson %T Behaviour-based Knowledge Systems: An Epigenetic Path from Behaviour to Knowledge %X In this paper we expose the theoretical background underlying our current research. This consists in the development of behaviour-based knowledge systems, for closing the gaps between behaviour-based and knowledge-based systems, and also between the understandings of the phenomena they model. We expose the requirements and stages for developing behaviour-based knowledge systems and discuss their limits. We believe that these are necessary conditions for the development of higher order cognitive capacities, in artificial and natural cognitive systems. %D 2002 %K evolution of cognition, behaviour-based systems, knowledge-based systems %L cogprints2320
