Argumentative Relation Classification as Plausibility Ranking
Table 3: Precision and recall scores for each class on Essay-Content. underlined: best result; bold: improves against SVM withstanding standard deviation.
['System', '[ITALIC] Attack Precision', '[ITALIC] Attack Recall', '[ITALIC] Support Precision', '[ITALIC] Support Recall']
The very rare attack-class is detected with a much greater precision compared with the SVM. The difference can range from an improvement of 5.6 pp. (ArgRankerY/N, relative improvement: 28%) up to a maximum improvement of 31.4 pp. (ArgRankervote, relative improvement: 157%). With such a large increase in precision, one might expect a drop in recall – however, this is only the case to a very small extent.
