TAILIEUCHUNG - Báo cáo khoa học: "Alternating Quantifier Scope in CCG*"

The paper shows that movement or equivalent computational structure-changing operations of any kind at the level of logical form can be dispensed with entirely in capturing quantifer scope ambiguity. It offers a new semantics whereby the effects of quantifier scope alternation can be obtained by an entirely monotonic derivation, without typechanging rules. | Alternating Quantifier Scope in CCG Mark Steedman Division of Informatics University of Edinburgh 2 Buccleuch Place Edinburgh EH8 9LW UK steedman@ Abstract The paper shows that movement or equivalent computational structure-changing operations of any kind at the level of logical form can be dispensed with entirely in capturing quantifier scope ambiguity. It offers a new semantics whereby the effects of quantifier scope alternation can be obtained by an entirely monotonic derivation without typechanging rales. The paper follows Fodor 1982 Fodor and Sag 1982 and Park 1995 1996 in viewing many apparent scope ambiguities as arising from referential categories rather than true generalized quantifiers. 1 Introduction It is standard to assume that the ambiguity of sentences like 1 is to be accounted for by assigning two logical forms which differ in the scopes assigned to these quantifiers as in 2a b 1 1 Every boy admires some saxophonist. 2 a. x y ỉ admires yx b. By .saxophonist y A x admires yx The question then arises of how a grammar parser can assign all and only the correct interpretations to sentences with multiple quantifiers. This process has on occasion been explained in terms of quantifier movement or essentially Early versions of this paper were presented to audiences at Brown u. NYU and Karlový u. Prague.

Constants are distinguished from variables by a prime and semantic functors like admires are assumed to be Curried . A convention of left associativity is assumed so that admires yx is equivalent to
