Call for papers


An important aspect of Natural Language Processing (NLP) as an area of Artificial Intelligence is the question on the representation formalisms of the knowledge structures which serve as input and output to a NLP system. In the past, considerable attention has been given to "deep", language-independent formalisms and NLP applications. Recent NLP systems and applications show a tendency of using shallow representation formalisms, e.g., Information Extraction templates, shallow logical formalisms in open-domain question answering systems, XML-based representations for NL generation (NLG). The Semantic Web (SW) initiative bears an enormous potential for NLP with respect to the powerfulness and standardization of the input/output structure descriptions across different approaches to NL understanding and generation. This potential has hardly been explored as yet. The purpose of this workshop is to bring together researchers that are working in the area of Natural Language Processing and Semantic Web.


The proposed workshop will focus on the wide variety of research problems that relate to the problem of embedding of NLP components into the Semantic Web. These topics include, but are not limited to:
  • RDF/OWL as the knowledge representation formalism for NLP
  • SW-based interlingua representation level
  • NLP based on heterogenous meta data sources
  • ontology-annotation of syntactic treebanks
  • mapping linguistic and domain ontologies
  • integrated shallow and deep NLP for ontology extraction
  • NLP-techniques for ontology engineering
  • Differences/commonalities of ontology use for
  • NL understanding and generation
  • Controlled NLQuery Interfaces for Ontologies
  • ontology-based QA for interactive semantic search
  •  context-aware NL understanding and generation
  • semantic text summarization
  • NLP based on distributed ontologies


The Semantic Web (SW) is an emerging technology that wants to bring content into the current Web, by associating meta-data to arbitrary web resources, like web pages, pictures, data sheets etc. SW consists of meta-data and links to global ontologies, which serve as structural vocabularies for the interpretation of domain-specific terms. It is widely accepted that Language Technology, especially Information Extraction is a core technology for the extraction and creation of semantic content. LT hence gains increased importance in the SW-community. As long as the human user is in the "Internet Loop", Natural language (NL) will remain to be the core Human-SW communication device. In the future, humans will continue to exchange knowledge via NL documents - with semantically annotated documents serving as the core Human-SW interface. In this context, NL understanding and generation methods and applications are needed for allowing an effective machine-user content-oriented interaction, as well as a context sensitive production of human-readable and understandable content in form of "natural" NL, e.g., NL-summarization from heterogeneous resources, dynamically created reports, magazines, newspapers, or the personal digital memory. So far, NLP, especially NLG has not gained much attention in the context of the Semantic Web, possibly also due to the very initial state of meta-data creation. However, with the emergence of ontology standards and
the development of large-scale annotated resources, NLP from and to meta-data will receive increased importance. The workshop will be of major interest to researchers interested in Language Technology, shallow and deep NLP, and Semantic Web. Furthermore, we expect that it will attract people working on Information Extraction, Question Answering and other related fields.

Submission Instructions

The program committee welcomes submissions of long papers for full plenary presentation, as well as short papers for presentation during a poster session. All papers must describe original, previously unpublished research. Papers that are being submitted to other conferences or workshops must indicate this explicitly on the title page. Long papers should be no more than 8 pages inclusive of all references and figures, and short papers should be no more than 4 pages inclusive of all references and figures. The programme committee may suggest the acceptance of a long paper as a short paper.

All papers must be submitted in PDF. It is the responsibility of the authors to ensure that the submitted papers print correctly on a variety of printers. If any special fonts are used, they must be included in the submission.

The deadline for the submission of both long and short papers is 15th April 2006. All submissions must be made electronically to The style and format to use for papers and abstracts is the same as for ECAI with the difference that papers need not be anonymised. Please follow the ECAI formatting instructions. The title page (no separate title page is needed) should include the following information:
  • Title
  • Authors' names, affiliations, and email addresses
  • 3-5 relevant keywords
  • Abstract (short summary up to 5 lines)
