This paper reports some findings following the analysis of the effects that different settings of centering parameters have on Chinese discourse anaphora resolution,especially in those unresolved cases.First,algorithms based on Centering Theory in general are more effective for zero anaphora resolution than for pronominal anaphora resolution.Second,Cb continuity is not a predominant factor in determining the salience of discourse entities.Third,Cf ranking scheme that takes into consideration both the grammatical roles and hierarchical sentence structures can more accurately reflect the salience of discourse entities.Fourth and last,accurate and reliable parsing of Chinese sentences is a prerequisite for anaphora resolution.
