From Durrett & Klein (2014)[1]: "ACE 2005 corpus (NIST, 2005): this corpus annotates mentions complete with coreference, semantic types (per mention), and entity links (also per mention) later added by Bentivogli et al. (2010). [...] train/test split from Stoyanov et al. (2009), Haghighi and Klein (2010), and Bansal and Klein (2012)."
