Syntax Matters for Rhetorical Structure: The Case of Chiasmus

The chiasmus is a rhetorical figure involving the repetition of a pair of words in reverse order, as in “all for one, one for all”. Previous work on detecting chiasmus in running text has only considered superficial features like words and punctuation. In this paper, we explore the use of syntactic features as a means to improve the quality of chiasmus detection. Our results show that taking sy...

Structure-sensitive NP-interpretation: A case study in Tagalog

Using Tagalog as a case study, this paper provides an analysis of a cross-linguistically well attested phenomenon, namely, cases in which a bare NP’s syntactic position is linked to its interpretation as definite or indefinite. Previous approaches to this phenomenon, including analyses of Tagalog, appeal to specialized interpretational rules like Diesing’s Mapping Hypothesis. I argue that such ...

On Worst-Case to Average-Case Reductions for NP Problems

We show that if an NP-complete problem has a non-adaptive self-corrector with respect to a samplable distribution then coNP is contained in NP/poly and the polynomial hierarchy collapses to the third level. Feigenbaum and Fortnow (SICOMP 22:994-1005, 1993) show the same conclusion under the stronger assumption that an NP-complete problem has a non-adaptive random self-reduction. Our result show...
