In this paper, we present a novel ap- proach for identifying argumentative dis- course structures in persuasive essays. The structure of argumentation consists of sev- eral components (i.e. claims and premises) that are connected with argumentative re- lations. We consider this task in two consecutive steps.

For both tasks, we evaluate several classifiers and propose novel feature sets including struc- tural, lexical, syntactic and contextual fea- tures. In our experiments, we obtain a macro F1-score of 0.726 for identifying argument components and 0.722 for argu- mentat...
