Abstract
BLANC is a link-based coreference evaluation metric for measuring the quality of
coreference systems on gold mentions. This paper extends the original BLANC
(“BLANC-gold” henceforth) to system mentions, removing the gold mention assumption.
The proposed BLANC falls back seamlessly to the original one if system mentions are
identical to gold mentions, and it is shown to strongly correlate with existing
metrics on the 2011 and 2012 CoNLL data.
