In both corpora we compare against the following previously proposed models: Base Classifier (Stab & Gurevych, 2016 ) is feature-rich, task-specific (AC type or link extraction) SVM classifier. Neither of these classifiers enforce structural or global constraints. Conversely, the ILP Joint Model<cite> (Stab & Gurevych, 2016)</cite> provides constrains by sharing prediction information between the base classifier.
