Due to its importance, pronoun resolution has seen a series of different approaches, such as rule-based systems (Lee et al., 2013) and end-to-end-trained neural models (Lee et al., 2017;Liu et al., 2019).
the recently released dataset GAP (Webster et al., 2018) shows that most of these solutions perform worse than naïve baselines when the answer cannot be deduced from the syntax.
