Evaluating Centering for Information Ordering using Corpora (2008)
Nikiforos Karamanis, Massimo Poesio, Chris Mellish, Jon Oberlander
In this paper 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...
Natural Language Processing in aid of FlyBase curators (2008)
Karamanis, Nikiforos, Seal, Ruth, Lewin, Ian, McQuilton, Peter, Vlachos, Andreas, Gasperin, Caroline, ...
Abstract Background Despite increasing interest in applying Natural Language Processing (NLP) to biomedical text, whether this technology can facilitate tasks such as database curation remains...
Entity versus Rhetorical Coherence for Information Ordering: Initial Experimentation (2008)
This paper investigates whether the model of local rhetorical coherence suggested in Knott et al. (2001) can boost the performance of the Centering-based metrics of entity coherence employed by...
Supplementing Entity Coherence with Local Rhetorical Relations for Information Ordering (2008)

Text mining is defined by Hearst (1999) as the automatic discovery of new, previously unknown, information from unstructured textual data. This is often seen as comprising of three major tasks:...
A Categorial Grammar for Greek (2007)
This paper presents a Categorial Grammar for Greek. The analysis provides evidence in favour of Set Combinatory Categorial Grammar (Set-CCG, Baldridge 2000), a formalism which shares the attractive...
PhD. Proposal: Centering Theory for Coherent Natural Language Generation (2007)
Centering Theory (Grosz et al. (1995); Walker et al. (1998a), inter alia) is an entity-based theory of local coherence. It has been conceived as a means of accounting for the processing costs imposed...
Ordered Set Combinatory Categorial Grammar (2007)
In this paper, we discuss data from Greek that provide evidence in favour of Set-CCG, a formalism which shares the attractive linguistic and computational aspects of CCG. Moreover, we suggest that,...

A CENTERING-BASED ALGORITHM FOR THE GENERATION OF THE ANIMATE SUBJECT IN GREEK (2007)
Centering Theory was originally discussed from the point of view of interpretation rather than generation and research tended to concentrate on anaphora resolution. In this paper, I rst review some...
THE USE AND USEFULNESS OF TEMPLATES IN CLASSIFICATION- BASED NATURAL LANGUAGE GENERATION (2007)
IDAS is a Natural Language Generation (NLG) system that produces on-line documentation for users of complex equipment. In this paper, I am going to present the architecture of the system and show how...
Integrating natural language processing with FlyBase curation (2007)

Evaluating centering for sentence ordering in two new domains (2006)
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...
Generating Multiple-Choice Test Items from Medical Text: A Pilot Study (2006)
We report the results of a pilot study on generating Multiple-Choice Test Items from medical text and discuss the main tasks involved in this process and how our system was evaluated by domain...

This paper surveys the corpus-based methods for evaluating Information Ordering (IO) which emerged recently in the literature on text production. First, we discuss how different assumptions about the...
This paper addresses two previously unresolved issues in the automatic evaluation of Text Structuring (TS) in Natural Language Generation (NLG). First, we describe how to verify the generality of an...
Entity Coherence for Descriptive Text Structuring (2004)
Although entity coherence, i.e. the coherence that arises from certain patterns of references to entities, is of attested importance for characterising a descriptive text structure, whether and how...
