Abstract

Starting from the assumption that a powerful temporal dimension is mandatory for bodiless agents (the rationale and approach is in three recent papers), the target is to develop agent-oriented mechanisms able to implant relevant temporal aspects into generic agent architectures. To be credible, such mechanisms must be validated in experimental models with two roles: a) serve as test-bench for long-range research undertakings (e.g., emulating agent self-awareness); b) set up a framework for designing non-trivial applications (e.g., virtual musicologist) in a dynamic domain (sound-based messages). The paper presents the second model of an agent that is able to interpret protensity-based messages, designed to act as an e-maieut (i.e. virtual guitar teacher). The approach is based on theories of internal representations of external objects (because protensity-based messages are treated as such objects). The focus is on mechanism effectiveness: the agent treats limited aspects of sounds involved in playing guitar (correctness of the scales played by the learner, freely or in the context of various chord progressions).
