A Performance Metric for Coreference Resolution: Constrained Entity-Alignment F-Measure (CEAF)

The paper proposes a Constrained Entity- Alignment F-Measure (CEAF) for coreference resolution based on the best one-one map between reference and system entities. An efficient algorithm is presented to compute the proposed metric. Problems associated with the MUC link-based F-measure (and its variation B-cube F-measure) are fixed in the proposed metrics. Compared with ACE-value, the official metric in the ACE task, the proposed metrics are easier to interpret.
