Categorial Semantics For LFG
نویسنده
چکیده
A categorial semantics for Lexical-khmctional Grammar provides a means for semantic interpretation of sentences of natural language that is appropriately constrained both syntactically and semantically. The f-structure of LFG provides a cross-lingnistically uniform format for representing syntactic information; constraining a derivation with respect to the f-structure rather than a phrase structure tree allows reference to relevant functional syntactic information without requiring construction of a phrase structure tree whose form is (often dubiously) motivated on semantic grounds. Additionally, a categorial semantics constrains semantic derivations appropriately, obviating the need for an appeal to wellformedness conditions on the resulting semantic representation.

Type-driven semantic interpretation and feature dependencies in R-LFG
This paper describes a new formalization of Lexical-Functional Grammar called R-LFG (where the “R” stands for “Resource-based”). The formal details of R-LFG are presented in Johnson (1997); the present work concentrates on motivating R-LFG and explaining to linguists how it differs from the “classical” LFG framework presented in Kaplan and Bresnan (1982). This work is largely a reaction to the ...
متن کاملInput and Glue in OT-LFG
In glue logic (Dalrymple 1999, 2001, Asudeh 2004), LFG has found a reasonably stable but developing method for connecting syntactic structures to formal semantic intepretation. However current formulations of glue logic make the rather unsatisfactory move of divorcing grammatical features from any intrinsic connection with what are usually regarded as their meanings. Rather than directly connec...
متن کاملSmall CCC’s as Logical Forms for LFG Glue Semantics
In this brief note I will present a way to adapt the ‘semantic interpretation as a functor’ idea introduced independently but in similar forms by Lambek (1988) and Dougherty (1993) for Categorial Grammar to the rather different environment of LFG glue semantics’ (Dalrymple (2001), Asudeh (2004) and many other works). Pollard Pollard (2004) presents a somewhat different conception of semantic in...
متن کاملScoping and Recursive Modification in TL-LFG
Type-Logical Lexical Functional Grammar (TL-LFG) combines the extreme lexicalism and tight relationship between syntactic and semantic construction of Type-Logical Categorial Grammar with the virtues of having functional structure at the core of syntactic analyses. This paper presents fragments of an analysis of modification in TL-LFG. Particular attention is given to the scope and ordering of ...
متن کاملEncoding LFG f-structures in the TL-LFG type system
Type-Logical Lexical Functional Grammar is a new syntactic framework similar in nature to Type-Logical Categorial Grammar, but with a distinct Lexical Functional Grammar flavour. It is the overall setup of TLLFG that makes it a close relative of TLCG, but it is the information encoded in the type system that brings it even closer to LFG. The encoding of f-structure information in the TL-LFG typ...
