摘　　要： 句法和语义对应的原则是形式语义学中最为重要的原则之一,组合范畴语法CCG更是彻底地延续了这个思想,为自然语言的计算机处理提供了句法和语义的透明接口。汉语的CCG处理在贯彻该原则时产生的问题是:句法方面获得长足进展,而语义方面却相对滞后。以汉语多重介词短语句为例,动词论元的灵活语序现象是句法和语义对应的难点之一。Hoffman提出的多重论元集CCG方法是解决灵活语序的有效手段,但在这种处理方法中,需要找出一些方法来简化形式语义的表述方式,这样才能获得与句法范畴推演相对应的语义类型推演。 The principle of syntax-semantics correspondence, or the principle of compositionality, is one of the golden rules in the formal treatment of natural language, which is thoroughly embodied in CCG. The common practice of CCG is as follows： in the lexicon of CCG, the basic expressions of NL （natural language） are labeled with an ordered pair of terms, the term of syntactic category and the semantic term. In the process of CCG＇s derivation, the concatenation of NL expressions has been changed into the parallelism of derivation of syntactic category and ）v-calculus. In NL processing, the treatment of CCG constitutes a transparent inter{ace between syntax and semantics of NL, because from the formal semantic point of view, the derivation of syntactic category which represents the syntactic construction of NL and the ）v-calculus which represents the semantic generation of NL by means of providing the indirect model-theoretic interpretations are two sides of the same coin. However, the problem of the CCG approach to Mandarin Chinese under this principle mainly lies in the fact that great progress has been achieved in the treatment of syntax while little progress in the treatment of semantics. Currently, in the CCG＇s studies on Mandarin Chinese, the researchers mainly explore the possibility of more effective and accurate syntactic parsing by means of giving proper syntactic rules and determining categorial assignment for the basic expressions according to their syntactic features. In contrast, whether such syntactic parsing is suitable for semantic representation is not their concern. Considering the close relation between syntax and semantics, the separation of syntactic parsing from semantic representation will decrease remarkably the significance of the syntactic parsing. For instance, the Mandarin Chinese sentence with prepositional phrases is noted for its flexible word order, which constitutes one of the challenges for CCG. As a tentative solution, Hoffman＇s multiset-CCG is introduced, which adher
