Scoring Metric: B-Cubed+

A clustering has high B-Cubed recall if, given an item, most of its coreferential items are in its cluster

A clustering has high B-Cubed precision if, given an item, most of the other items in its cluster are in fact coreferential with it

B-Cubed+ adds the constraint that links to existing items in the KB must also match
