These features are calculated by mining the parse trees, and then could be used for resolution by using manually designed rules (Lappin and Leass, 1994;Kennedy and Boguraev, 1996;Mitkov, 1998), or using machine-learning methods (Aone and Bennett, 1995;Yang et al., 2004;Luo and Zitouni, 2005).
to our knowledge, the application of such a technique to the pronoun resolution task still remains unexplored.
