Direct and Underspecified Interpretations of LFG f-structures

On Interpreting F-Structures as UDRSs

We describe a method for interpreting abstract fiat syntactic representations, LFG f-structures, as underspecified semantic representations , here Underspecified Discourse Representation Structures (UDRSs). The method establishes a one-to-one correspondence between subsets of the LFG and UDRS formalisms. It provides a model theoretic interpretation and an inferen-tial component which operates d...

A Deductive Account of Quantification in LFG

The relationship between Lexical-Functional Grammar (LFG) functional structures (f-structures) for sentences and their semantic interpretations can be expressed directly in a fragment of linear logic in a way that explains correctly the constrained interactions between quantifier scope ambiguity and bound anaphora. The use of a deductive framework to account for the compositional properties of ...

level of representation and permits grammaticality—as in usual LFG—to bedetermined on the phrasal and functional level of representation.A final note about the basic formal properties of the approaches. For traditional LFGgrammars (satisfying the Nonbranching Dominance Condition) the parsing problem isdecidable, since a grammar can assign to a string only a finite number of vali...

From Surface Dependencies towards Deeper Semantic Representations

In the past, a divide could be seen between ’deep’ parsers on the one hand, which construct a semantic representation out of their input, but usually have significant coverage problems, and more robust parsers on the other hand, which are usually based on a (statistical) model derived from a treebank and have larger coverage, but leave the problem of semantic interpretation to the user. More re...
