The standard preference ordering on the well-known centering transitions Continue, Retain, Shift is argued to be unmotivated: a partial, context-dependent ordering emerges from the interaction between principles dubbed cohesion (maintaining the same center of attention) and salience (realizing the center of attention as the most prominent NP). A new formulation of Rule 2 of centering theory is proposed that incorporates these principles as well as a streamlined version of Strube and Hahn's (1999) notion of cheapness. It is argued that this formulation provides a natural way to handle “topic switches” that appear to violate the canonical preference ordering.

Centering Theory

We describe a system for contextually appropriate anaphor and pronoun generation for Turkish. It uses binding theory and centering theory to model local and nonlocal references. We describe the rules for Turkish, and their computational treatment. A cascaded method for anaphor and pronoun generation is proposed for handling pro-drop and discourse constraints on pronominalization. The system has been tested as a stand-alone nominal expression generator, and also as a reference planning component of a transfer-based MT system.

Newspaper Articles

The aim of the paper is to map various types of anaphor to the centering transitions in the corpus of Serbian newspaper articles. Centering Theory (WALKER, JOSHI ET AL. 1998) is a theory of local coherence in which four types of transitions are used as parameters of coherence. As is hypothesized in the previous literature based on various languages, the CONTINUE transition is mostly characterized by a minimal form (a zero form of the topic), while the SMOOTH and ROUGH shifts are found with a full noun phrase topic. The analysis shows that the ?Ordering Rule? of Centering Theory is not fully followed in the written corpus of the Serbian language since SMOOTH SHIFT has been identified as a prevalent type of transition in the corpus. The following two reasons were identified for that: (1) the genre of the newspaper articles, and (2) the way clauses are combined within a complex sentence in the Serbian written corpus.

In this article we discuss several metrics of coherence defined using centering theory and investigate the usefulness of such metrics for information ordering in automatic text generation. We estimate empirically which is the most promising metric and how useful this metric is using a general methodology applied on several corpora. Our main result is that the simplest metric (which relies exclusively on NOCB transitions) sets a robust baseline that cannot be outperformed by other metrics which make use of additional centering-based features. This baseline can be used for the development of both text-to-text and concept-to-text generation systems.

This paper is concerned with how <em>there</em>-constructions may have helped to achieve discourse coherence in the recent history of English. From the theoretical framework of Meta-Informative Centering Theory (MIC) the paper explores the possibility to establish a relation between the syntactic structures under analysis and the distinction between 'smooth-shift' and 'rough-shift' transitions from one centre of attention to another (Brennan, Friedman &amp; Pollard, 1987). This will help, ultimately, to investigate the interaction between centering and MIC theories, word order and information structure in a 'non-free' word order language such as English. A corpus- driven analysis of the behaviour of spoken and written <em>there</em>-constructions from late Middle English to Present Day English will show their capacity to function either as highly coherent structures that continue with the same local topic as the previous utterance(s), or as means to shift the local focus of attention.
