A primitives-based approach to knowledge acquisition

GAS, a primitives-based generic knowledge acquisition shell which allows users to easily construct and then execute a domain-specific knowledge acquisition tool for specific problem domains, is described. It contains problem solving primitives, acquisition primitives, interaction primitives, representation schemas, learning primitives, and knowledge processing primitives in order to construct specific knowledge acquisition tools efficiently. This approach relieves knowledge engineers from selecting and applying different knowledge acquisition tools for different domains. GAS has been developed as an open architecture so that further enhancement can be done easily
