摘要
本文讨论了"零形代词"在汉语中的定义和识别标准,认为零形代词不仅包括谓词和述谓结构中缺省的支配成分和主语,还应包括为保持话题链中的话题延续而省略的零形代词。通过对比分析两种零形代词定义对汉语指代消解结果的影响,本文得出如下结论:添加零形话题后,1)零形代词的消解准确率得到显著提高;2)代词的消解准确率在以小句切分语句时也有显著提高,但在以自然句切分语句时并无影响。原因分析显示,添加零形话题有利于突显话题链中话题的延续,体现局部篇章中的实体连贯,从而有利于零形代词的消解和代词在小句中的消解。
This paper first discusses the definition of zero pronoun （ZP） in Chinese, and argues that it should include not only the null argument of a verb and subject of a non-verbal predicate, but also the zero topic of a clause in a top- ic chain. We then carry out an empirical study to examine the effects of the two definitions of ZP in anaphora resolu- tion. It is found that, with additional annotation of zero topics in the data, 1 ） the precision rates of ZP resolution have been significantly raised; and 2） the results of pronoun resolution have also been significantly improved when the cen- tering parameter of ＂Utterance＂ is defined as a clause （ U1 ）, but no effect is found when it is defined as a natural sentence （ U2 ）. An examination of the reason behind this result reveals that the recognition of zero topics highlights topic continuity in a topic chain and better reflects entity coherence in local discourse, thus facilitating the resolution of ZP and pronoun under U1.
