Abstract Abstract: There exists a general consensus that the most salient discourse entity—those entities that are currently at the center of attention—tend to be referred to with the most reduced referring expressions, in most cases a pronoun. Here comes the question that is crucial for anaphora resolution: what kinds of factors influence a referent’s saliency and how to evaluate it effectively? In Beaver’s Centering Optimality Theory (COT), the grammatical role is the major determinant of the ranking on salience weight, which diminishes the precision of resolution to some degree. In this study, four factors that have been claimed to influence salience are examined with abundant examples: (1) information status, (2) view-point effect, (3) referential form, and (4) parallel effect. They are then transformed into constraints of Evaluator in COT so as to improve its performance in anaphora optimization.
