Implementation and Visualization of Conceptual Graphs in CharGer

Abstract

Practitioners using conceptual graphs are naturally interested in tools that support its features. The CharGer editing software has been available for many years, giving the community a chance to evaluate and contribute to CharGer's ever-expanding capabilities. As result of that experience, the author discusses a few lessons learned about visualization and implementation of conceptual graphs. Features such as actors, glossary integration, standards-based interoperability and automatic layout offer opportunities to study and improve the usefulness of conceptual graphs tools.
