Neural Coreference Resolution for Arabic
This addresses the problem of coreference resolution for Arabic NLP, but it is incremental as it adapts an existing method to a new language.
The authors tackled the lack of a neural coreference resolution system for Arabic by introducing the first such system, which outperforms the existing state-of-the-art on OntoNotes 5.0 with a gain of 15.2 points in CoNLL F1.
No neural coreference resolver for Arabic exists, in fact we are not aware of any learning-based coreference resolver for Arabic since (Bjorkelund and Kuhn, 2014). In this paper, we introduce a coreference resolution system for Arabic based on Lee et al's end to end architecture combined with the Arabic version of bert and an external mention detector. As far as we know, this is the first neural coreference resolution system aimed specifically to Arabic, and it substantially outperforms the existing state of the art on OntoNotes 5.0 with a gain of 15.2 points conll F1. We also discuss the current limitations of the task for Arabic and possible approaches that can tackle these challenges.
