组合范畴语法CCG|与汉语空代词现象的处理

Study on the Combinatory Categorial Grammar and Tackling of Empty Pronoun Phenomenon in Chinese Grammar

处理照应回指现象一直是范畴语法所关注的重点和难点。汉语中的空代词几乎可以出现在代词所能出现的任何合法位置,并且空代词与话题具有不对称性,处理起来更为困难。在组合范畴语法CCG中增加关于照应的一些规则和省略槽规则,得到组合范畴语法CCG|,能有效地处理汉语空代词及其照应现象。仅当空代词现象是由语义资源重复使用而造成的删略方可使用省略槽规则,因移位造成的语缺需另寻他法。

The treatment of anaphoric phenomenon is always the key and difficult point in categorical grammar. Empty pronouns in Chinese can occur almost in any legal position where pronoun can. It is very difficult to deal with empty pronouns and the topic because they are asymmetric. The author adds some anaphoric rules and an ellipsis slot rule to combinatory categorical grammar(CCG) and can effectively deal with Chinese empty pronouns and anaphoric phenomena. The paper concludes that only when the empty pronouns result from the use of cut slightly for the semantic duplication of resources can the ellipsis slot rules be used, and other empty pronoun phenomena resulting from the movement need to find another way.
