Conceptual Graphs: cg@cs.umn.edu Conceptual Graphs are a general semantic network representation of knowledge invented by John Sowa. They have the expressive power of logic, but with an easy mapping to natural language. See, for example, John F. Sowa, "Conceptual Structures: Information Processing in Man and Machine", Addison-Wesley, Reading, Mass, 1984. John Florian Sowa, "Knowledge Representation", forthcoming.
