ACL-IJCNLP'09 Workshop on Language Generation and Summarisation ===============================================================


Language Generation and Summarisation (UCNLG+Sum) is a post-conference workshop at ACL-IJCNLP 2009, Singapore, on 6 August 2009.

Background ----------

There are many branches of NLP research which involve the generation of language (summarisation, MT, human-computer dialogue, application front-ends, data-to-text generation, document authoring, etc.). However, it is not always easy to identify common ground among the generation components of these application areas, which has sometimes made it difficult for generic research in `Natural Language Generation' (NLG) to engage with them effectively. Recent advances in corpus-based approaches across many of these areas, and in particular in NLG itself, offer a new perspective on this problem and the opportunity to explore synergies and differences from the common grounding of corpus data.

This workshop is the third in an occasional series seeking to exploit this opportunity by providing a forum for discussing NLG and its links with these closely related fields from a corpus-oriented perspective. These workshops have the general aims:

1. to provide a forum for reporting and discussing corpus-oriented

methods for generating language;

2. to foster cross-fertilisation between NLG and other fields of

research involving generation of language; and

3. to promote the sharing of data and methods in all research that

involves the generation of language.

Each of these workshops has a special theme: at the first workshop (at Corpus Linguistics in 2005) it was the use of corpora in NLG, at the second (at MT Summit XI in 2007) it was Language Generation and Machine Translation. The special theme of the 2009 workshop is Language Generation and Summarisation.

Aims of this Workshop ---------------------

There are two basic approaches to text summarisation: abstractive, where texts are analysed, and a more condensed version is regenerated, and extractive, where key passages of the input texts themselves are identified and then `glued together' to form a shorter text. Extractive summarisation is less dependent on analysis and regeneration techniques, but tends to produce summaries that are not very coherent and whose referring expressions are not very clear (so for example, extractive systems often score low on the DUC human assessment criteria of Coherence and Referential Clarity).

The relevance of NLG techniques to abstractive summarisation is clear, but recently there has also been increasing interest in regeneration as a post-process for extractive summaries. Work by Otterbacher et al., Steinberger et al. and Nenkova et al., for example, shows how regeneration of (parts of) extractive summaries may help to increase their coherence, referential clarity or fluency. At the same time, NLG researchers are investigating techniques that could be used to improve extractive summaries by regenerating them (in particular in the subfield of referring expression generation, see for example the GREC Shared Task papers at INLG 2008).

The core aim of this workshop is to provide a forum for NLG and summarisation researchers to examine the similarities and differences between their current approaches to generating language, and to explore the potential for cross-fertilisation.

Topics of Interest ------------------

We invite submissions on all aspects of using corpora in the generation of language, with a particular interest in relevance to text summarisation. Specific topics include, but are not limited to:

- generation techniques in abstractive summarisation

- regeneration/rewriting/post-processing techniques for extractive


- generation of references to named entities in discourse context

- annotating corpora for language generation and summarisation

- uses of corpora in the evaluation of language generation and

summarisation systems

- reuse of corpus resources developed for NLU (e.g. treebanks) in

language generation and summarisation

- domain-specific vs. general-purpose corpora for language generation

and summarisation

- statistical approaches to language generation and summarisation

- machine learning methods for language generation and summarisation

Requirements ------------

Papers should describe original and unpublished work, emphasizing actual rather than intended work, and should indicate clearly the state of completion of the reported work. Wherever appropriate, concrete evaluation results should be included. Papers that are being submitted to other conferences or workshops should indicate this.

Submission information ----------------------

Submissions should be no longer than 8 (eight) pages, and should follow the ACL-IJCNLP 2009 guidelines using the style files provided at http://www.acl-ijcnlp-2009.org/main/authors/stylefiles/. Papers should be submitted in PDF format using the START submission website for the workshop at https://www.softconf.com/acl-ijcnlp09/UCNLGSum/. The deadline for submission is 1 May 2009.

Each paper will be reviewed by at least three programme committee members. Final decisions on the technical programme will be made by the workshop organisers.

As reviewing will be blind, papers should not include the authors' names and affiliations. Self-references that reveal the authors' identity, e.g., "We previously showed (Smith, 1991) ...", should be avoided. Instead, use citations such as "Smith previously showed (Smith, 1991) ...". Acknowledgments sections should be removed before submission.

Proceedings -----------

The proceedings of the workshop will be edited by the workshop organisers and published by the ACL-IJCNLP 2009 conference organisers.

Important Dates ---------------

01 May 2009 Deadline for papers submissions 22 May 2009 Notification of acceptance to authors of workshop papers 07 June 2009 Camera-ready copies due 06 August 2009 UCNLG+SUM workshop in Singapore

Invited Speaker ---------------

Kathy McKeown, Columbia University, USA.

Panel on Common Ground between Summarisation and Language Generation --------------------------------------------------------------------

Panelists t.b.a.

GREC'09 Challenges Special Session ----------------------------------

UCNLG+Sum will host the results session of this year's GREC Shared Task Competitions which are part of the Generation Challenges initiative. The first is the GREC-MSR (Main Subject Reference) Task which uses the GREC-2.0 Corpus of 2,000 Wikipedia introduction sections in which references to the main subject of the Wikipedia article have been annotated, and the task is to develop a system that can select (from a given list) an MSR that is appropriate in the context. The second is the GREC-NEG (Named Entity Generation) Task which uses the new GREC-People Corpus of 1,000 Wikipedia introduction sections about people in which single and plural references to all people mentioned in the text have been annotated. The task in GREC-NEG is to select appropriate referential expressions for all mentions (singular and plural) of people.
