Abstract

The current work presents the participation of UBIU (Zhekova and Kübler, 2010) in the CoNLL-2012 Shared Task: Modeling Multilingual Unrestricted Coreference in OntoNotes (Pradhan et al., 2012). Our system deals with all three languages: Arabic, Chinese and English. The system results show that UBIU works reliably across all three languages, reaching an average score of 40.57 for Arabic, 46.12 for Chinese, and 48.70 for English. For Arabic and Chinese, the system produces high precision, while for English, precision and recall are balanced, which leads to the highest results across languages.
