    In this work we introduce a scheme to handle unknown user arguments in argumentative Dialogue Systems. We consider systems based on argument games and a graph representation of argument components and discuss how a component that is not present in the latter one can be included reasonably. The proposed approach also allows for a differentiation between invalid input and new arguments as well as a reasonable system response in the latter case.
