While the coreference results in Table 6 seem to suggest that SCA and mention should be employed as constraints, the resolution results in Table 7 sug-gest that SCA is better encoded as a feature.
(1) in comparison to the baseline, the accuracy of common NP resolution improves by about 5-8% when SCA is encoded as a feature; and (2) whenever SCA is employed as a feature, the overall resolution accuracy is significantly higher for resolvers that use SCs induced by DL and SVM than those that rely on Soon's method for SC determination, with improvements in resolution observed on all three NP types.
