语篇中代词指代的研究进展

代词的指代在语篇局部连贯性中具有关键作用。中心理论是代词指称中的重要理论，它解释了语篇中代词的分布规律；注意驱动理论是在中心理沦的基础上结合重音预设解释重音或非重音代词。影响代词指称的因素有语义因素和结构因素。对代词的认知研究另一方面主要集中在对歧义代词的解释．对歧义代词的解释的研究一方面采用重复姓名不利实验范式，另一方面的研究采用的研究方法是探测词任务。在汉语中对代词的研究主要是对文本语篇的研究。

Progress in Pronominal Expression in Discourse

It is widely recognized that pro nouns play a critical role in promoting the loca l coherence of discourse. The centering theory attempts to synthesize and extend the und erstanding of how pronouns are distributed. The attention-based theory tries to interprete accented or unaccented pronouns. Factors leading to the in terpretation o f pronon referential expression are found to be of two sorts: semantic and structure. Besides, by comparing comprehension o f pronominal coreference and repeated-name coreference in cases where the coref e rential interpretation is unambiguous, studies have demonstrated a repeated -name penalty. Probe-word tasks have been assigned in the studies,too. The stu dies of pronoun referential expression in Chinese have focused on text.
