=====================================================================

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.
