Alternative Knowledge Acquisition Interface Structures

摘要

This reserach developed a design concept for an interactive system to acquire domain knowledge form a training expert. Such a system would facilitate the development of knowledge-based instructional systems by directly eliciting and encoding from domain experts knowledge needed to deliver instruction. An analysis of the process by which knowledge-based systems are constructed indicates that the generality of a knowlege acquisition system must be limited by domain characteristics and by the architecture of the system it serves, and the non-sequential, interacting activities during system development constrain the potential role of automated knowledge acquisition aids. A feasible concept for knowledge acquistion technology, building on prior research in artificial intelligence, involves the notion of class-generic systems for a related set of domains with a fixed architecture and training capabilities. This concept is developed and discussed in the context of proposed Navy training systems for acquiring models of trainee performance during learning, rules of behavior for an automated opponent in a tactics trainer, and a knowledge base of facts to be subsequently presented to trainees for memorization.
