A conceptual graph (CG) is a formalism for knowledge representation. In the first published paper on CGs, John F. Sowa used them to represent the conceptual schemas used in database systems.^[1] The first book on CGs applied them to a wide range of topics in artificial intelligence, computer science, and cognitive science.^[2]
