@article{mugnier1996reprsenter, abstract = {We briefly present our point of view about conceptual graphs: graphs with ordered labels - for representing knowledge - with graph operations - for reasoning. We propose a formalism for simple conceptual graphs which generalizes the usually considered model, and preserves its fundamental properties. Links with important combinatorial notions (graph morphism, Constraint Satisfaction Problems) are established. Finally a notion of nested conceptual graph is fonnally defined, which significantly extends the simple model. }, address = {Lavoisier}, author = {Mugnier, Marie-Laure and Chein, Michel}, howpublished = {Cachan, FRANCE}, interhash = {36420c3d29d5cac23213a9a53e743a95}, intrahash = {d09f701711d74256bc1c4a373eb6eebd}, journal = {Revue d'Intelligence Artificielle}, number = 1, pages = {7-56}, series = 1, title = {Représenter des connaissances et raisonner avec des graphes}, volume = 10, year = 1996 }
