A Multimedia Knowledge Representation for an 'Intelligent' Computerized Tutor.
Abstract
The intended end product of our current research project is an 'intelligent' multimedia tutoring system for procedural tasks, and in particular, for repair of physical objects. This paper presents the data structure that will be used. It is a graph with five types of nodes (mental, abstract, motoric, or action, visual, and verbal) and two types of links (subconcept and pointer). The graph examples given in the paper are knowledge representations of conceptualizations that people might have for a simple object, a flashlight. We show how the representations are used for choosing actions, planning strategies, making inferences, and designing instructions. We give the plan for computer implementation of the tutoring system. We report previous applications of this knowledge representation, including how it can be de rived from experimentally observed behavior. And we compare our knowledge representation to others. Keywords: Multimedia knowledge representation, Data structure for computer implementation, Performing procedures.
