17-20 June 2007


Schloss Dagstuhl, Germany

(preceding ACL 07 in Prague)
 Sponsored by SIGGEN

Special Interest Group on Generation (SIGGEN)

The Workshop                                                                                                                                                            Top

Natural language generation (NLG) is a subfield of natural language processing that focuses on the generation of written texts in natural languages from some underlying non-linguistic representation of information, generally from databases or knowledge sources. Accomplishing this goal may be envisioned for a number of different purposes, including standardized and/or multi-lingual reports, summaries, machine translation, dialogue applications, and embedding in multi-media and hypertext environments. Consequently, NLG is associated with a large number of highly diverse tasks whose appropriate orchestration in high quality poses a variety of theoretical and practical problems. Relevant issues include content selection, text organization, production of referring expressions, aggregation, lexicalization, and surface realization, as well as coordination with other media. 

The workshop continues a biennial series of workshops on natural language generation that has been running since 1987. Previous European workshops have been held at Toulouse, Budapest  and Aberdeen. The series provides  a regular forum for presentation of research in this area, both for NLG specialists and for researchers from other areas.

The 2007 workshop will span the interest areas of Natural Language Generation to Artificial Intelligence, Computational Linguistics and Pycholinguistics as well as to any neighbouring area. One of the key themes will be evaluation of NLG systems, including two sessions on recent activities in this area.  

The invited speaker will be Dr Kristiina Jokinen. Kristiina's work focusses on adaptive interactive systems, including dialogue and, of course, NLG. She will talk about her views of evaluating NLG systems.  


Topics of Interest                                                                                                                                                      Top

We welcome papers on formal, corpus-based, implementational and analytical work on conventional NLG topics (content selection, planing, realisation, etc), and especially papers with a focus on the following themes:

  •      NLG workflows and architectures
  •      NLG for real-world applications
  •      Multilingual NLG
  •      Use of ontologies in NLG
  •      NLG in linguistically motivated frameworks
  •      Statistical processing for NLG
  •      Information organization for planning and NLG
  •      Evaluation of NLG systems

We also welcome discussion on the challenges that these viewpoints pose for generation systems and applications, as well as new ideas and solutions for general frameworks. Especially, we invite research papers and system descriptions on applying natural language generation in solutions to real-world problems.


Submissions (closed)                                                                                                                                              Top

Papers must describe original work. Long papers describe mature contributions, whereas short papers describe ideas or system implementations. If the same content is under review for another publication, this should be indictaed. 

Submissions should be in two-column A4 format. Margins should be set so that the text appears as a rectangle of 16.5 x 23 cm. Please use only classic fonts such as Times Roman oder Computer Modern. Use 11 pt for the text, 14 or 16 pt for headings and titles. Do not paginate your paper, we will do this when putting together the proceedings. Pictures can span both columns.  The Association for Computational Linguistics (ACL) has provided a LaTeX style [file], which should be used for submission. This file was altered slightly to suit our needs. For the bibliography, use the [acl.bst]  BibTeX file. MS-Word users should work from this ACL [template].

Long papers must not exceed 8 pages, short papers are up to 4 pages long. Submit papers to the [EasyChair] website. Alternatively, if this does not work for you, you can send your paper as a PDF document to [enlg07 at]. The Subject Line should contain the words "ENLG07 Submission".

Moreover the proceedings are available from the [ACL Anthology].

The list of accepted papers can be found [here], and the preliminary workshop programme is available [here]

A featured topic at ENLG07 has been evaluation of NLG systems from diverse viewpoints. This includes 

  • Shared-task evaluation, introduced by Robert Dale and Anja Belz,  
  • Quality of service and communicative competence in NLG evaluation, presented by Kristiina Jokinen in her keynote talk, and 
  • Ample opportunity for discussion.
In order to lend structure to the discussions, we have identified key topics of interest in advance, and invited community members with a particular interest in a topic to act as topic leaders. The role of a topic leader will be to present the topic briefly, lead group discussions and, together with other discussion group members, prepare a few slides summarising the group's work.

We will concentrate on the following topics;  the topic leaders' names are put in brackets:
  • Extrinsic/task-based evaluation of language (Ehud Reiter)
  • Evaluation of language generation in dialogue systems (Kristiina Jokinen)
  • Common input specifications for NLG (Helmut Horacek)
  • Sharing components and resources (Roger Evans)
For the schedule, see the [workshop programme].
