Embodied conversational agent based on the dual cognitive architecture

Abstract

A working model of an ECA with cognitive capabilities based on the DUAL cognitive architecture is described. The cognitive model used inherits the advantages of a high context-sensitivity, general and episodic memory, and reasoning by analogy of the DUAL/AMBR model. However, several crucial new mechanisms are proposed which allow for the continuous functioning of the agent and the completion of several question-answer cycles with meaningful priming and context effects. This paper presents these mechanisms and discusses the results of simulations of a user-agent interaction session.
