Scope Economy and TAG Locality
نویسنده
چکیده
This paper gives an analysis explaining various cases where the scope of two logical operators is non-permutable in a sentence. The explanation depends on a theory of derivational economy couched in the synchronous tree adjoining grammar framework. Locality restrictions made using the STAG formalism allow us to limit the computational complexity of using transderivational constraints and allows us to make interesting empirical predictions.

Cosubstitution, Derivational Locality, and Quantifier Scope
Quantifier scope challenges the mantra of Tree Adjoining Grammar (TAG) that all syntactic dependencies are local once syntactic recursion has been factored out. The reason is that on current TAG analyses, a quantifier and the furthest reaches of its scope domain are in general not part of any (unicomponent) elementary tree. In this paper, I consider a novel basic TAG operation called COSUBSTITU...
متن کاملOn the Form-Meaning Relations Definable by CoTAGs
Adding cosubstitution to the classical TAG operations of substitution and adjunction, coTAGs have been proposed as an “alternative conceptualization” to resolve the tension between the TAG mantra of locality of syntactic dependencies and the seeming non-locality of quantifier scope. CoTAGs follow the tradition of synchronous TAGs (STAGs) in that they derive syntactic and semantic representation...
متن کاملCoTAGs and ACGs
Our main concern is to provide a complete picture of how coTAGs, as a particular variant within the general framework of tree adjoining grammars (TAGs), can be captured under the notion of abstract categorial grammars (ACGs). coTAGs have been introduced by Barker [1] as an “alternative conceptualization” in order to cope with the tension between the TAG-mantra of the “locality of syntactic depe...
متن کاملModelling the ziji Blocking Effect and Constraining Bound Variable Derivations in MC-TAG with Delayed Locality
MC-TAG derivations using delayed locality (i.e. non set-local composition) have been used to model long distance binding in natural language. In this paper, I explore the possibility within Synchronous TAG that tree sets composing via delayed locality may have many possible syntactic derivations for a single semantic form. Using the Mandarin (Chinese) anaphor ziji as a test case, I show that th...
متن کاملScrambling in German and the non-locality of local TDGs
Existing analyses of German scrambling phenomena within TAG-related formalisms all use non-local variants of TAG. However, there are good reasons to prefer local grammars, in particular with respect to the use of the derivation structure for semantics. Therefore this paper proposes to use local TDGs, a TAG-variant generating tree descriptions that shows a local derivation structure. However the...
