Several features of spoken dialogue systems require advanced reference resolution strategies. This paper presents a knowledge–based strategy for reference resolution implemented over an agent architecture which differentiates the Knowledge and Action Managers from the Dialogue Manager. The strategy, in conjunction with the ability of the Dialogue Manager to manipulate the dialogue history, has ...

Van der Sandt s anaphoric account of presupposition is gen erally considered to be the theory which makes the best empiri cal predictions about presupposition projection see e g Beaver The main insight is that there is an interesting cor respondence between the behavior of anaphoric pronouns in dis course and the projection of presuppositions in complex sentences Van der Sandt proposes to resol...

The present paper conducts a pioneering study on the phonetic manifestation and influence of zero anaphora in Chinese reading texts. The stress degree of the boundary syllable and the duration of the pause at the anaphoric position are examined. The results show: i) the boundary syllable after zero anaphoric form is more accented; for the two types of zero anaphora concerned in this study, the ...

In this paper, we explore how the taxonomic inheritance hierarchy in a semantic net can contribute to the resolution of associative anaphoric expressions. We present the results of some preliminary experiments and discuss both their implications and the scope for improvements to the technique.

We present a pilot experiment to measure the effects of redundancy in the resolution of definite descriptions as performed by a small number of human readers. Although originally intended to provide evidence of how much redundancy should ideally be included in generated anaphoric descriptions, preliminary findings reveal a number of little explored issues that are relevant to both referring exp...

A variety of approaches to annotating reference in corpora have been adopted. This paper reviews four approaches to the annotation of reference in corpora. Following this we present a variety of results from one annotated corpus, the UCREL anaphoric treebank, relevant to automated reference resolution.

We def ine anaphora more broadly than is usua l l y done, i . e . to inc lude not only pronoun, proadverb ( e . g . he re , t h e r e , t hen ) , pro-verb (e .g . do as in John goes to bed e a r l y ; I do t o o . ) , d e f i n i t e , e t c . re fe rence, but a lso i n d e f i n i t e reference (as in 1 below),as w e l l as reference by an e n t i r e sentence or subsentence to a previous sent...

We present an implemented system for the resolution of it, this, and that in transcribed multi-party dialog. The system handles NP-anaphoric as well as discoursedeictic anaphors, i.e. pronouns with VP antecedents. Selectional preferences for NP or VP antecedents are determined on the basis of corpus counts. Our results show that the system performs significantly better than a recency-based base...

This paper describes our work in query-based multi-document summarization task in DUC2006. We present the system overview, focusing on the newly developed techniques, including a new method of sentence similarity calculation, and application of anaphoric resolution to improve the readability of the summary. Evaluation results from NIST are also given and analyzed.
