The MARGIE system is a set of three programs that attempt to understand natural language. They are based on the Conceptual Dependency system for meaning representation. The analysis program maps sentences into conceptual structures. The memory program makes inferences from input conceptual structures. The generator codes conceptual structures back into natural language. Together the programs function as a paraphrase and inference system.
