MOLE: A Tenacious Knowledge-Acquisition Tool

Abstract MOLE can help domain experts build a heuristic problem-solver by working with them to generate an initial knowledge base and then detect and remedy deficiencies in it. The problem-solving method presupposed by MOLE makes several heuristic assumptions about the world, which MOLE is able to exploit when acquiring knowledge. In particular, by distinguishing between covering and differentiating knowledge and by allowing covering knowledge to drive the knowledge-acquisition process, MOLE is able to disambiguate an under-specified knowledge base and to interactively refine an incomplete knowledge base.
