For instance, the raw hit counts of the preposition pattern query (e.g., arrangements of products) for a bridging anaphor a and its antecedent candidate e is the maximum count among all instantiations of e. In our experiments, we simply extend the list of antecedent candidates E a (described in Section 4) to include all instantiations of the original entities in E a .
