[PDF] Top 20 Translation Based Projection for Multilingual Coreference Resolution

... To align English and French words, we trained a word alignment model using GIZA++ 5 (Och and Ney, 2000) on a parallel corpus comprising the English-French section of Europarl 6 (Koehn, 2005) as well as all the French ... See full document

... easier to resolve than common noun phrases and pronouns. To leverage this, we follow Sapena et al. (2010) who reorder mentions based on mention type. Specifically, we first process proper noun phrases, then common ... See full document

... The results of this experiment show that im- provements in MHD translate directly into im- provements of the overall CR system. Since the ML approach outperforms the rule-based ap- proach for two languages, we can ... See full document

... The OntoNotes corpus has been used for eval- uating end-to-end CR systems at two CoNLL shared tasks (2011 and 2012). At the 2011 shared task, the participants relied on rule-based mod- ules for extracting mention ... See full document
