(2015), along with our novel multi-focal attention model to enforce coherence, leading to significant performance improvements on CoNLL 2003 (Hoffart et al., 2011) and TAC KBP 2010-2012 tasks (Ji et al., 2010;Ji et al., 2011;Mayfield et al., 2012).
we achieve a 20% relative reduction in error from Chisholm and Hachey (2015) on CoNLL, and a 22% error reduction from Cucerzan (2012) on TAC 2012.
