Bridging resolution plays an important role in establishing (local) entity coher- ence. This paper proposes a rule-based approach for the challenging task of unre- stricted bridging resolution, where bridg- ing anaphors are not limited to defi- nite NPs and semantic relations between anaphors and their antecedents are not re- stricted to meronymic relations. The sys- tem consists of eight rules which target different relations based on linguistic in- sights. Our rule-based system significantly outperforms a reimplementation of a pre- vious rule-based system (Vieira and Poe- sio, 2000). Furthermore, it performs better than a learning-based approach which has access to the same knowledge resources as the rule-based system. Additionally, incorporating the rules and more features into the lear...
