A number of schemes have appeared recently which learn structural concepts from examples, thereby offering the potential to interact directly with domain experts to acquire knowledge. This paper examines the fundamental distinctions which underlie current research, relates them to plain questions about the capabilities of learning systems, and critically reviews representative systems from the perspective of practical knowledge acquisition.EngComputer Scienceunknown1987-253-0110.11575/PRISM/31149
