Therefore, we use our BA-SIC model to prune antecedent choices for each a i in order to reduce the size of the factor graph that we must instantiate.
we prune links between pairs of mentions that are of mention distance more than 100, as well as values for a i that fall below a particular odds ratio threshold with respect to the best setting of that a i in the BASIC model; that is, those for which is below a cutoff γ.
