Meaning versus Grammar

This volume investigates the complicated relationship between grammar, computation, and meaning in natural languages. It details conditions under which meaning-driven processing of natural language is feasible, discusses an operational and accessible implementation of the grammatical cycle for Dutch, and offers analyses of a number of further conjectures about constituency and entailment in natural language

Filtering Left Dislocation Chains in Parsing Categorial Grammar

This paper reports on a way to reduce the complexity of the process of left dislocation (re)construction for categorial grammar in the case of lexically assigned gaps, as an additional restriction on the complexity arising from lexical polymorphism in general. Specifying extraction sites lexically has the advantage that the combinatory explosion can be contained in the preparsing track by a specialized constraint on the expansion of sequences of categories. This constraint is called the Left Dislocation Chain Filter and is implemented by a Finite State Transducer. It is shown that the Filter can reduce the number of full string assignments under consideration prior to parsing with an average of one half to one order of magnitude, depending on the nature of the sentence. 1 Parsing Left Dislocation Left dislocation is a very common, almost universal phenomenon in natural languages. It establishes the relation between an element at the left periphery of a clause and a particular, lexical..

Pruning Search Space For Parsing Free Coordination In Categorial Grammar

The standard resource sensitive invariants of categorial grammar are not suited to prune search space in the presence of coordination. We propose a weaker variant of count invariancy in order to prune the search space for parsing coordinated sentences at a stage prior to proper parsing. This Coordinative Count Invariant is argued to be the strongest possible instrument to prune search space for parsing coordination in categorial grammar. Its mode of operation is explained, and its effect at pruning search space is exemplified. 1 1 Lexical Ambiguity and Natural Language Parsing Lexical ambiguity is known to be a major threat to efficient parsing of natural language. It is easy to see why. Let G NL be a grammar for a language NL, and L a lexicon with initial assignment A of nonterminals to the words of NL. Let S = w 1 ... w n be a sentence over L. Under a parsing-as-deductionapproach, then, the parsing problem for S is whether for some sequence C = c 1 ... c n , with c Î A(w ), C is der..
