ACL/EACL 2001 Workshop 8th EUROPEAN WORKSHOP ON NATURAL LANGUAGE GENERATION 6-7 July 2001 Toulouse, France http://www.cs.unca.edu /%7Ebruce/acl01/NLG.html ------------------------------------------------------------------------ Natural language generation (NLG) constitutes the production of meaningful texts in natural languages from some underlying non-linguistic representation of information. Accomplishing this goal may be envisioned for a number of different purposes, including standardized and/or multi-lingual reports, summaries, machine translation, dialog applications, and embedding in multi-media and hypertext environments. Consequently, the automated production of language 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, the production of referring expressions, aggregation, lexicalization, and surface realization, as well as coordination with other media. This workshop is part of a bi-annual series of workshops about natural language generation that runs since 1987. Previous European workshops have been held at Royaumont, Edinburgh, Judenstein, Pisa, Leiden, Duisburg, and Toulouse. The goal of the workshop is to be an informal meeting which facilitates the dissemination of knowledge and expertise in the field. The workshop will focus on the following topics: * Search methods for NLG (in content planning and realization) There seems to be a substantial discrepancy between application-oriented systems and principled approaches to NLG. Accomodating a standard pipeline architecture with suitable heuristic preferences to the intended functionality of a system stands in contrast to several principled approaches to searching which have been tried out so far. These include blackboard architectures, constraint propagation and, more recently genetic algorithms and statistical techniques. A comparison of these methods in terms of their potential and limitations is likely to improve understanding about this issue. Gained insights could prove fruitful for building applications in a more general and, thus, better reusable way, especially in large-scale applications such as summarization and machine translation. * Differences in information organization between source and presentation specifications (and methods to bridge between these) Whether the generation task is to verbally express contents of some knowledge base or to produce multi-lingual presentations from language-neutral or similar representations, there are strong similarities in building the target representations: In the overwhelming number of cases, the ordering and embedding of elements in the source representation is reflected by the ordering and embedding of their corresponding realizations at the surface. Often, this reflection is systematic, many times even simple. But a few cases prove complex and involve a major restructuring of the surface structure when compared to the source structure. A major emphasis of this topic is on collecting such complex cases, identifying commonalities between them and discussing restructuring techniques. Accepted papers on these topics will be scheduled for presentation. The majority of the time will be devoted to discussions, either in sequence or in parallel, depending on the number of participants. We are considering organizing a panel. For the focus topics above, we will contact a number of competent researchers to address the topic from a specific perspective according to their experience. In addition, we will ask some of them to prepare material / concrete examples for discussions. WORKSHOP CHAIRS Helmut Horacek Univ. of the Saarland Nicolas Nicolov IBM T.J.

Papers should be 6-8 pages long in PDF format. We recommend a A4, two-column format like the ACL proceedings: http://acl2001.dfki.de/style/ We also invite poster submissions (free format, up to 6 page, PDF). The submissions should be associated with a cover email containing the following information (ASCII text): - TITLE: < title of the paper > - AUTHORS: < list of authors > - EMAIL: < email of author(s) for correspondence > - KEYWORDS: < keywords, topic sub-areas, ... > - ABSTRACT: < abstract of the paper > Send your submission to Leo Wanner <wannerlo_(on)_informatik.uni-stutt gart.de>. IMPORTANT DATES Paper submissions *** 6 April 2001 *** Notification of acceptance 27 April 2001 Camera-ready copies due 16 May 2001 Registration deadline as ACL Workshop dates 6-7 July 2001 REGISTRATION The registration fee for the workshop will be posted at a later stage. The registration fee includes attendance of the workshop and a copy of workshop proceedings. Follow the registration instructions at the ACL site and indicate that you would like to attend the NLG workshop. People wishing to attend the workshop but not submitting papers should send a notification of attendance: a 1-2 page stating interest to participate, work done in NLG so far, and potential contributions / material for discussions about one of the topics. This informationn will help with the organisation of discussions and allow for an informal and highly interactive character of the workshop. Notifications of attendance should be sent to Helmut Horacek <horacek_(on)_cs.uni-sb.de>. MORE INFORMATION Check the following web site for updates about the NLG workshop:
