摘　　要：本文采用向心理论的参数化研究方法,根据影响前瞻中心排序的一些主要因素设计了6种算法,对比分析了不同排序方法对英汉指代消解的影响。研究发现,整体而言:1)语法功能在两种语言中都比线性语序更准确地反映了前瞻中心显著度;2)在按语法功能排序的基础上,考虑语法功能平行性对英汉零形代词消解具有一定优势,考虑回指中心连贯性对英汉代词消解具有一定优势,同时考虑两者的算法具有更广泛的优势;3)按语法功能排序,并同时考虑语法功能平行性和句子层级结构,对英汉零形代词和汉语代词消解都可以获得最佳结果,而对英语代词消解却会产生消极的影响。This paper adopts the parametric approach to the Centering Theory and designs 6 algorithms to examine the effects of the different setting of the Centering parameter'Cf-ranking'on the results of anaphora resolution in Chinese and English.The results show that,overall,1)in both languages grammatical function is a better indicator of Cf salience than linear order;2) integrating syntactic parallelism and Cb continuity into grammatical function ranking may have its advantage in ZP and PRON resolution respectively,and the combination of the two gets a wider edge in the resolution of both ZP and PRON in the two languages;and 3)ranking Cfs according to grammatical function and at the same time taking both syntactic parallelism and hierarchical structure into consideration can achieve best results for ZP resolution in both languages and for Chinese pronoun resolution,but may produce a negative effect on English pronoun resolution.
