Centering theory posits a discourse center, a distinguished discourse entity that is the topic of a discourse. A simplified version of this theory is developed in a Dynamic Semantics framework. In the resulting system, the mechanism of center shift allows a simple, elegant analysis of a variety of phenomena involving sloppy identity in ellipsis and “paycheck pronouns”.

self-centering pier (scp) has been viewed as a remarkable accomplishment which is able to sustain major lateral loading with reduced structure damage in seismic engineering. stiffness deterioration observed in experiment is vital for the seismic performance of self-centering concrete pier. in this contribution, the associated stiffness deterioration with respect to the structural damage is mode...

Data matrix centering is an ever-present yet under-examined aspect of data analysis. Functional analysis (FDA) often operates with a default such that the vectors in one dimension have mean zero. We find along other identifies novel useful mode variation beyond those familiar FDA. explore ambiguities both orientation and nomenclature. Differences between centerings their potential interaction c...

This paper builds on recent research investigating sentence ordering in text production by evaluating the Centering-based metrics of coherence employed by Karamanis et al. (2004) using the data of Barzilay and Lapata (2005). This is the first time that Centering is evaluated empirically as a sentence ordering constraint in several domains, verifying the results reported in Karamanis et al.

A central claim of centering theory (Grosz, Joshi, and Weinstein, 1995, henceforth GJW) is that certain entities mentioned in an utterance are more central than others, and that this property imposes constraints on a speaker’s use of different types of expressions to refer to them. To articulate some of these constraints, they define several fundamental centering concepts and propose rules base...

Inequalities for martingales with bounded differences have recently proved to be very useful in combinatorics and in the mathematics of operational research and computer science. We see here that these inequalities extend in a natural way to ’centering sequences’ with bounded differences, and thus include for example better inequalities for sequences related to sampling without replacement. 1 C...

Since pronouns can be dropped in Thai, a natural language processing system for Thai must be able to resolve referents of the missing pronouns. One of several approaches that have been used for reference resolution is Centering Theory. Centering Theory is a focusing process in which salience of discourse entities is being kept track of. Referents of pronouns or zero pronouns are usually entitie...
