Abstract: This paper reports on the systems the RuG Team submitted to the GermEval 2018 - Shared Task on the Identification of Offensive Language in German tweets. We submitted three systems to Task 1, targeting the problem as a binary classification task, and only one system for Task 2, addressing a fine-grained classification of offensive tweets in different categories. Preliminary evaluation of the systems has been conducted on a fixed validation set from the training data. The best macro-F1 score for Task 1, binary classification, is 75.45, obtained by an ensemble model composed by a Linear SVM, a CNN, and a Logistic Regressor as a meta-classifier. As for Task 2, multi-class classification, we obtained a macro-F1 of 40.75 using a multi-class Linear SVM.

Erfahrungsaustausch auf hohem Niveau durch die Vorstellung
computerlinguistischer Grundlagenforschung und ausgewählte
Praxisvorträge von Experten befördern.
