The Expressive Power of Restricted Fragments of English

Allan Third

Taking the notion of of a language to mean its ability to distinguish different situations, we define four simple fragments of English based on the syntactic constructions they contain, and characterise their expressive power via translation into first-order logic. We also describe the circumstances under which an arbitrary first-order formula can be translated back into an English sentence of each fragment. This work is an extension of the semantic complexity results of Pratt-Hartmann [2] and Pratt-Hartmann [3].

The Complexity and Generative Capacity of Lexicalized Abstract Categorial Grammars

Ryo Yoshinaka; Makoto Kanazawa

Previous studies have shown that some well-known classes of grammars can be simulated by (de Groote 2001) in straightforward ways. These classes of grammars all generate subclasses of the PTIME languages. While the exact generative capacity of the class of ACGs and the complexity of its universal membership problem are both unknown, we show that the universal membership problem for the class of ACGs is NP-complete and the languages generated by lexicalized ACGs form a subclass of NP which includes some NP-complete languages.

More Algebras for Determiners

R. Zuber

Some new algebras, which are possible denotations for various determiners, are studied. One of them is the algebra of generalised cardinal quantifiers which is a sub-algebra of conservative quantifiers and which contains cardinal, co-cardinal and proportional quantifiers. In addition some non-conservative quantifiers are studied (symmetric, contrapositional and fixed points with respect to the post-complement). It is shown that co-intersective quantifiers are contrapositional. The analysis is extended to quantifiers of higher types.
