In this article, we provide different possibilities for doing reasoning on simple concept(ual) graphs without negations or nestings. First of all, we have on the graphs the usual semantical entailment relation |=, and we consider the restriction ⊩ of the calculus for concept graph with cuts, which has been introduced in [Da02], to the system of concept graphs without cuts. Secondly, we introduce a semantical entailment relation |= as well as syntactical transformation rules ⊩ between models. Finally, we provide definitions for standard graphs and standard models so that we translate graphs to models and vice versa. Together with the relations |= and ⊩ on the graphs and on the models, we show that both calculi are adequate and that reasoning can be carried over from graphs to models and vice versa.
