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

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.
