A method is proposed for argumentation on the basis of information that characterizes the structure of arguments. The proposed method cein be used both to detect arguments emd to generate candidate arguments for rebuttal. No assumption of a priori knowledge about attack and support relations between propositions, advanced by the agents participating in a dialog, is made. More importantly, by using the method, the relations are dynamically established while the dialog is taking place. This aJlows incremental processing since the agent need only consider the current utterance advanced by the dialog participant, not necessarily the entire argument, to be able to continue processing.
