UNITS

The frame-based UNITS system was developed in the MOLGEN project as a general-purpose knowledge representation, acquisition, and manipulation tool. Designed for use by domain experts with little previous knowledge of computers, it provides an interface that allows the expert to describe both factual and heuristic knowledge. It contains both domain-independent and domain-specific components, including modified English rules for describing the procedural knowledge. UNITS has been licensed by Stanford University for commercial development. (1975-1981)
