A Multimedia Knowledge Representation for an "Intelligent" Computerized Tutor. Technical Report No. 142.
Baggett, Patricia; Ehrenfeucht, Andrzej
The intended end product of the research project described is an "intelligent" multimedia tutoring system for procedural tasks, in particular, the repair of physical objects. This paper presents the data structure that will be used, i.e., 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, e.g., a flashlight. Use of the representations is shown for choosing actions, planning strategies, making inferences, and designing instructions. The plan for computer implementation of the tutoring system is also given, as well as a report on applications of this knowledge representation, including how it can be derived from experimentally observed behavior. Finally, this knowledge representation is compared with others such as KRL, Pavio, and linguistically based theories. (Author/JB)
