Also, for a fixed value of β, BASIC-P1 β gives better MUC-F1 than BASIC-Pa β , and BASIC-Pa β gives better pairwise-F1 than BASIC-P1 β for both data sets.
in experiments on two coreference data sets, structured local training reduces the error rate significantly (3.5%) for one coreference data set and minimally (≤ 1%) for the other.
