Constructive knowledge engineering

摘要

Knowledge engineering research has shifted from the transfer, expert-driven metaphor for system development to an interpretative, model-driven metaphor. The paper examines the relationship between these two metaphors and introduces a third: constructive, problem-driven engineering. The paper postulates a theoretical construction of the interrelationships between these in terms of the epistemology of expertise, the engineering process, and representational issues. The constructive approach is further illuminated with example systems, and a set of guidelines for applying the constructive approach is provided.
