His view was that people should be able to build models in logic much like modern designers build models of airplanes for reasoning about real airplanes. Conceptual graphs are intuitive because they allow humans to exploit their powerful pattern matching abilities to a larger extent than does the classical notation. Conceptual graphs can be viewed as an attempt to build a unified modelling language and reasoning tool. Conceptual graphs can model data, functional and dynamic aspects of systems. They form a unified diagrammatic tool which can integrate Entity-Relationship diagrams, Finite State Machines, Petri Nets, and Dataflow diagrams.
Conceptual graphs have a natural mapping to natural language.
Argument for or against the use of conceptual graphs is of particular interest. This may be done by comparisons with other representations on the basis of expressiveness, intuitive aspect, ease of use, computational performance, or reasoning simplicity. Comparisons can also be made by translating existing case studies, which use well-known representations, into conceptual graphs. Shorter, substantive papers are welcome.
