Our goal in this paper is to annotate and make publicly available a corpus of persuasive student essays that addresses the aforementioned weaknesses via designing appropriate annotation schemes and scoring rubrics.
not only do we score the persuasiveness of each ar-gument in each essay (rather than simply the persuasiveness of the overall argument), but we also identify a set of attributes that can explain an argument's persuasiveness and annotate each argument with the values of these attributes.
