近年来,已经提出了各种各样的表示形式主义,以支持欠指定的语义表示,如准逻辑形式,欠指定的逻辑形式,欠指定的话语表示理论,最小递归语义,本体混杂,洞语义,Lambda结构的约束语言,和正常优势约束的建设。这些形式主义支持欠规范的方法,这些方法有时看起来非常不同,但实际上有相似的基本概念,在其他情况下,使用相同的术语但有不同的解释,看起来很相似。例如,UDRT和正常优势约束,乍一看似乎很不同,但仔细检查后有很多共同之处;另一方面,术语“元变量”被不同的作者用来指代不同的欠规范形式主义中的不同概念。最近的研究产生了有趣的结果,这些形式主义的相对表达能力。例如,Koller(2004)已经表明,在某些条件下,洞语义的欠指定表示可以转换为正常的优势约束,反之亦然。Ebert(2005)已经表明,最突出的用于表示范围现象的欠规范形式主义都缺乏表达能力。本文的目的是促进理解的各种欠规范形式主义的优点,考虑不同的欠规范技术提供了一系列的现象,激励使用欠规范的语义表示处理。
In recent years a variety of representation formalisms have been proposed that support the construction of underspecified semantic representations, such as Quasi-Logical Form, Underspecified Logical Form, Underspecified Discourse Representation Theory, Minimal Recursion Semantics, Ontological Promiscuity, Hole Semantics, the Constraint Language for Lambda Structures, and Normal Dominance Constraints. These formalisms support methods of underspecification which sometimes seem very different but in fact have similar underlying concepts, and in other cases appear deceptively similar, using the same terminology but with different interpretations. UDRT and Normal Dominance Constraints, for example, at first blush seem quite different but upon closer inspection have much in common; on the other hand, the term ‘metavariable’ is used by different authors to refer to different concepts in different underspecification formalisms. Recent studies have produced interesting results about the relative expressive capabilities of some of these formalisms. Koller (2004) has for instance shown that under certain conditions the underspecified representations of Hole Semantics can be translated into normal dominance constraints, and vice versa. Ebert (2005) has shown that the most prominent underspecification formalisms for the representation of scopal phenomena all suffer from lack of expressive power. This paper aims at contributing to the understanding of the merits of the various underspecification formalisms by considering what different underspecification techniques have to offer for dealing with a range of phenomena that motivate the use of underspecified semantic representations.
