Free versus bound variables and the taxonomy of gaps

Potts (Nat Lang Linguist Theory 20:623–689, 2002a) et seq. presents an analysis of gap-containing supplements (primarily, as-parentheticals) where the gap is modelled as a variable over the semantic type of the constituent that the as-clause adjoins to (the anchor). This much allows the meaning of the gap to be resolved purely compositionally, by defining as as a function that allows the anchor to bind the gap variable. This article presents a class of as-clauses where Potts’s analysis seems to break down, in that the gap cannot be modelled as a variable over the semantic type of the anchor. I propose that these cases can be unified with those in Potts’s work, as well as a larger class of ellipsis phenomena, by assuming that, under certain conditions, surface gaps are composite entities, containing a bound variable and a free variable that are resolved independently of each other. The bound variable is bound by the anchor (just as in Potts’s account), and the free variable is resolved by anaphora to a salient discourse object.

自由变量与有界变量以及差距分类法

Potts(Nat Lang Linguist Theory 20:623–689,2002a)等。提出了对包含缺口的补语(主要是-括号)的分析,其中将缺口建模为as子句邻接的成分(锚点)的语义类型上的变量。通过定义允许锚点绑定间隙变量的函数,这可以使间隙的含义完全由组成部分解决。本文介绍了一类作为-子句Potts的分析似乎崩溃了,因为无法将差距建模为锚点语义类型上的变量。我建议可以将这些情况与Potts的情况以及更大范围的省略号现象统一,方法是假设在某些条件下,表面间隙是复合实体,包含一个绑定变量和一个自由变量,它们可以独立求解彼此的。绑定变量由锚点绑定(就像在Potts的帐户中一样),而自由变量通过回指法解析为一个重要的话语对象。
