The results show a pattern which has also been shown in other results reported with other evaluation sets (Raghunathan et al., 2010), namely, the fact that a large part of the performance of the multi-pass sieve system is based on a set of significant sieves.
this module so far focuses on a subset of sieves only, namely, Speaker Match, Exact Match, Precise Constructs, Strict Head Match and Pronoun Match (Lee et al., 2013).
